Asked in companies
Given two sequences, find the length of longest subsequence present in both of them. A subsequence is a sequence that appears in the same relative order, but not necessarily contiguous.
Problem approach
This is a standard Dynamic programming question. I solved it using 2D DP by comparing current characters and filled DP using previous DP fields.

0/40
Two numbers A and B are said to be Co-Prime or mutually prime if the Greatest Common Divisor(GCD) of them is 1. You have been given two numbers A and B, find if they are Co-prime or not.
Problem approach
I simply calculated GCD of two numbers using the Euclid algorithm and just check the GCD whether it is one or not. If it is 1 then they are co-prime else not.
