ARR = [2,...read more
Ans. 
Find the second largest element in an array of integers. Return -1 if second largest does not exist.
• Iterate through the array to find the largest and second largest elements.

• Handle cases where all elements are identical by returning -1.

• Consider edge cases like empty array or array with less than 2 elements.

Q1. 
Idempotent Matrix Verification
Determine if a given N * N matrix is an idempotent matrix. A matrix is considered idempotent if it satisfies the following condition:
M * M = M
Input:
The first line cont...read more
Ans. 
Check if a given matrix is idempotent by verifying if M * M equals M.
• Calculate the product of the matrix with itself and compare it with the original matrix.

• If the product equals the original matrix, then it is idempotent.

• Iterate through the matrix elements to perform the necessary calculations.

Ans. 
Check if a given array contains a valid triplet where two elements sum up to the third.
• Iterate through all possible triplets in the array and check if any of the conditions are satisfied.

• Use nested loops to compare each element with every other element in the array.

• Handle cases where the elements are not distinct by ensuring i != j, j != k, and i != k.
