Maximize item collection using a sliding window approach on a 1D axis.
Identify the range of positions on the x-axis where items are located.
Use two pointers to represent the current window of positions being considered.
Expand the right pointer to include more items until the window exceeds the desired range.
Contract the left pointer to reduce the window size while maintaining the maximum sum of items.

Flow diagram of Wafer Test cases
Start with wafer preparation
Perform electrical testing on each die
Check for defects and record results
Sort dies based on test results
End with final wafer disposition
Test cases should cover various scenarios to ensure software quality.
Test case for positive scenario
Test case for negative scenario
Test case for boundary value testing
Test case for error handling
Test case for performance testing
Bit manipulation involves using bitwise operations to solve problems efficiently, often related to integers.
Bitwise AND (&) can be used to check if a bit is set. Example: 5 & 1 = 1 (binary 101 & 001).
Bitwise OR (|) sets a bit. Example: 5 | 2 = 7 (binary 101 | 010 = 111).
Bitwise XOR (^) toggles bits. Example: 5 ^ 3 = 6 (binary 101 ^ 011 = 110).
Left shift (<<) multiplies by 2. Example: 5 << 1...
The task involves manipulating an array of strings to achieve a specific goal.
1. Define the array: e.g., `String[] names = {"Alice", "Bob", "Charlie"};`
2. Iterate through the array using a loop to access each element.
3. Perform operations like filtering, sorting, or modifying elements.
4. Example: To find names starting with 'A', use a conditional check inside the loop.
Pseudo code for a scenario
Define variables and data structures needed
Write the main logic using conditional statements and loops
Handle edge cases and error conditions
Test the pseudo code with sample inputs
Extract data from a dynamic array and perform mathematical operations on it.
Identify the dynamic array structure, e.g., ['12', '15', '20'].
Convert string elements to integers for mathematical operations.
Perform operations like sum, average, or product on the extracted data.
Example: For array ['2', '3', '5'], sum = 2 + 3 + 5 = 10.
Use built-in functions like map() for conversion and reduce() for aggregation.
Prepare by gathering information from stakeholders, exploring the application, creating test scenarios, and using exploratory testing.
Gather information from stakeholders to understand the purpose of the application.
Explore the application to identify key functionalities and potential areas of risk.
Create test scenarios based on the observed behavior and potential user interactions.
Use exploratory testing to uncov...
Software testing is the process of evaluating a software application or system to identify defects or errors.
Software testing is essential to ensure the quality and reliability of software.
It involves executing test cases and comparing the actual results with expected results.
Testing can be done manually or using automated tools.
Types of testing include functional, performance, security, and usability testing.

Clone a linked list with random pointers.
Create a new node for each node in the original list.
Store the mapping between the original and cloned nodes in a hash table.
Traverse the original list again and set the random pointers in the cloned list using the hash table.
Return the head of the cloned list.
I am asked to give the coding test and tech questions on resume and job description
I applied via LinkedIn and was interviewed in Nov 2024. There was 1 interview round.
What is machine learning
I applied via Approached by Company and was interviewed in Aug 2024. There was 1 interview round.
2 problem was given to solve
1) Smallest Negative balance - -----%20America%20-%20Weekly%20Algorithm%20Challenges/Week%2021%20Algorithm%20Challenge/Smallest%20Negative%20Balance.md
2) Find the absolute difference between alpha & beta from the array.
Alpha -An element k in a array occurs k consecutive time
Beta - An element k in an array occurs k consecutive time starting from index k
Sample input
Arr[] = {2,2,2,4,4,4,4,1,2,2]
Output
Alpha - 3
Beta - 1
Absolute difference - 1
Note : consider array index starts with 1
