Round duration - 120 minutes
Round difficulty - Easy

This was the first round and it consisted of MCQs and programming questions. This round was difficult.

Q1. 
Longest Palindromic Substring Problem Statement
You are provided with a string STR of length N. The task is to find the longest palindromic substring within STR. If there are several palindromic substring...read more
Ans. 
Given a string, find the longest palindromic substring within it, returning the one that starts with the smallest index if multiple substrings qualify.
• Iterate through the string and expand around each character to find palindromes

• Keep track of the longest palindrome found so far

• Return the longest palindromic substring that starts with the smallest index

Q2. 
0-1 Knapsack Problem Statement
A thief plans to rob a store and can carry a maximum weight 'W' in his knapsack. There are 'N' items, with the i-th item weighing wi and having a value vi. Determine the max...read more
Ans. 
The 0-1 Knapsack Problem involves maximizing the value of items in a knapsack while respecting weight constraints.
• Iterate through all possible combinations of items to find the optimal solution.

• Use dynamic programming to store and reuse subproblem solutions.

• Consider the weight limit and value of each item to make the best choice.

• Example: For input [1, 2, 3], [10, 15, 40], and weight limit 6, the maximum value is 55.
