+# Bank Account
+
+You are given a simplified multi-threaded “bank account” implementation used by one of our infrastructure teams. The current code processes deposits concurrently but produces incorrect results.
+

+class BankAccount:
+    def __init__(self, balance):
+        self.balance = balance
+
+    def deposit(self, amount):
+        new_balance = self.balance + amount  # read
+        time.sleep(0.1)                      # simulate delay
+        self.balance = new_balance           # write
+

+
+with ThreadPoolExecutor(max_workers=2) as executor:
+    futures = [
+        executor.submit(account.deposit, 500),
+        executor.submit(account.deposit, 700),
+    ]
+```
+
+Task
+
+Identify the concurrency bugs in the implementation.
+
+Explain why these bugs occur.
+
+Fix the implementation without modifying the existing BankAccount class directly.
+
+You may use subclassing (Python) or embedding (Go-style composition), depending on the language you choose.
+
+Ensure your solution is thread-safe and produces the correct final balance (1200).

+# Bucket questions 
+
+## Context
+
+Please implement two functions: refillTokenBucket and useTokens. Two classes are already defined: DistributedCache and TokenBucket.
+
+refillTokenBucket(user_id): Refill tokens for the specified user's bucket.
+
+useTokens(user_id, tokens): Check if there are enough tokens in the specified user's token bucket. If so, update the remaining token count and return true; otherwise, return false. You are required to use instances of the existing classes to implement these functions.
+
+## Requirements
+
+Use the API provided by DistributedCache to get and update the user's TokenBucket.
+Implement the functionality using existing class instances and ensure the behavior is correct across multiple calls

+# Design an in-memory key-value database that supports the following commands and fully handles nested transactions.
+
+## Core Operations:
+SET <key> <value>: Sets the value for a key.
+
+GET <key>: Returns the value for a key.
+
+UNSET <key>: Removes the key and its value.
+
+## Transaction Operations:
+BEGIN: Starts a new transaction scope. If a transaction is already active, this starts a nested transaction.
+
+COMMIT: Applies all changes made in the current transaction scope and all its active nested transactions to the parent scope (or to the main database state if no parent exists). After a successful commit, the transaction scope is closed.
+
+ ROLLBACK: Discards all changes made in the current transaction scope and all its active nested transactions, restoring the state to what it was when the BEGIN command was issued for the current scope. After a successful rollback, the transaction scope is closed.
+
+## Implementation Goal:
+
+Design the primary data structures and outline the logic for SET, COMMIT, and ROLLBACK to ensure nested transactions operate correctly. Explain how the state of the database is managed across multiple transaction layers.

+Frontend Task
+
+1. Component Implementation: Enhanced TypeAhead (Good?)
+
+Develop a TypeAhead input component that filters a dataset based on user entry. Implement a debounce mechanism to optimize performance by limiting the frequency of function execution during typing. Apply text processing logic to identify and visually highlight the specific substrings within the results that match the user's input.
+
+2. Algorithmic Challenge: Increasing Subsequence(Okay?)
+
+Analyze a given array of integers and write a function to determine the length of the longest subsequent growing sequence contained within the array.
+
+3. Frontend Architecture: AI Prompt and Context Interface
+
+Construct a dual-pane user interface featuring a prompt history sidebar on the left and a main content area on the right for input and context display. Implement data fetching from the OpenAI API. Develop state management logic where submitting a new prompt triggers an API call, and selecting a specific prompt from the history injects the corresponding past response to serve as the context for the subsequent request.

+Inference Questions
+
+Context
+
+You are tasked with building a simplified inference engine component responsible for handling incoming user requests for a large language model (LLM). To optimize throughput and GPU utilization, the engine must batch multiple requests together, run the inference call once per batch, and then deconstruct the results to return token-level output to the individual users.
+
+Objective
+
+Complete the provided Python class, BatchInferenceEngine by implementing the methods necessary to:
+Queue incoming user requests.
+Process a batch when the queue reaches a defined batch size.
+
+Simulate the token-level output from an LLM and correctly associate each generated token with its original request.
+
+
+Task Requirements
+
+
+
+
+
+Implement the logic for $enqueue\_request$.
+
+
+
+Implement the logic for $\_process\_batch$.
+
+
+
+Demonstrate the usage by creating 7 unique requests and enqueueing them one by one. Show the state of the queue and the processed tokens after each batch run.

+# Bazel Firebase Cloud Messaging (FCM) example
+
+FCM requires certain information about your app (API key, app ID, project id,
+etc) to be present in the `res/values/values.xml` resource file. This example
+shows how to use the tools provided in the
+[bazelbuild/tools_android](https://github.com/bazelbuild/tools_android) repo to
+generate the `values.xml` file from the `google-services.json` file from your
+Firebase console.
+
+## Building the Example
+
+To build the example:
+
+1. Make sure the `ANDROID_HOME` environment variable is set to the absolute path
+   of your Android SDK.
+
+2. Go to the Firebase console for your project, and in Settings, download
+   `google-service.json`, and replace the sample file in the `app` directory.
+
+3. Run `bazel build //app` in the project.
+
+## Applying the Example to Your Code
+
+To apply this example to your code:
+
+1. Add the following to your `WORKSPACE` file:
+```python
+TOOLS_ANDROID_VERSION = "0.1"
+http_archive(
+  name = "tools_android",
+  strip_prefix = "tools_android-" + TOOLS_ANDROID_VERSION,
+  url = "https://github.com/bazelbuild/tools_android/archive/%s.tar.gz" % TOOLS_ANDROID_VERSION,
+)
+load("@tools_android//tools/googleservices:defs.bzl", "google_services_workspace_dependencies")
+google_services_workspace_dependencies()
+```
+
+2. Add the following to your `BUILD` file:
+```python
+load("@tools_android//tools/googleservices:defs.bzl", "google_services_xml")
+
+GOOGLE_SERVICES_XML = google_services_xml(
+  package_name = "com.example.myapplication",
+  google_services_json = "google-services.json"
+)
+```
+
+3. Add `GOOGLE_SERVICES_XML` to the `resource_files` attribute of your
+   `android_binary` rule. For example:
+```python
+android_binary(
+  ...
+  resource_files = glob(["src/main/res/**"]) + GOOGLE_SERVICES_XML,
+  ...
+)
+```
+
+4. Bazel's `AndroidManifest.xml` merging logic does not merge permissions from
+   dependent libraries (see issue [#5411](https://github.com/bazelbuild/bazel/issues/5411)).
+   You may need to add the following permissions to the `AndroidManifest.xml` of
+   your top-level `android_binary` rule:
+```xml
+<uses-permission android:name="android.permission.INTERNET" />
+<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
+<uses-permission android:name="android.permission.WAKE_LOCK" />
+<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
+```
+
+## Manual Integration
+
+It's also possible to run the Google Services values.xml generator manually and
+add the results to your project:
+
+1. Go to the Firebase console for your project, and in Settings, download
+   `google-service.json`.
+
+2. From the workspace root of the `tools_android` project, run the Google
+   Services XML generator:
+```
+  bazel run //third_party/googleservices:GenerateGoogleServicesXml -- \
+     com.example.myapplication \
+     /absolute/path/to/google-services.json \
+     /tmp/values.xml
+```
+   The arguments are the package name for your app, the absolute file path to  
+   the `google-services.json` file, and finally the file path for `values.xml`.
+
+3. Merge the resulting `values.xml` file into your `values.xml` file (or put the
+   file into your `res/values` directory if you don't already have a
+   `values.xml` file). Alternatively, the `values.xml` file can be put into a
+   separate `res/values` directory and added to the `resource_files`. For the
+   example here, if `values.xml` is in
+   `app/src/main/google_services_xml/res/values/values.xml`, the `BUILD` file
+   would have
+   `resource_files = glob(["src/main/res/**"]) + ["src/main/google_services_xml/res/values/values.xml"],`.

+## Documentation
+
+For the full documentation, please visit the [Bazel documentation page](https://bazel.build/docs/android-ndk).
+
+## Instructions
+
+1) Launch emulator
+2) Run `bazel mobile-install //app/src/main:app --android_platforms=//:x86 --start_app`
+
+<img src="images/result.png" width="400px" />

+## Build graph
+
+![](/images/graph.png)
+
+- JNI/C++ sources goes into the `cc_library` target, `//app/src/main:jni_lib`.
+- Java sources, resource files, and assets go into the `android_library`
+  target, `//app/src/main:lib`. This target depends on the `cc_library` target.
+- The APK is built from the `android_binary` target, `//app/src/main:app`. This
+  target depends on the `android_library` target.
+
+NOTE: This graph omits the Google Maven AAR dependencies.
