- Given two arrays A, B and a required array wanted. You are given 8 functions each with a fixed length (example functions 1. Returns element in A (length 1) 2. Returns min of elements in A and element in B (length 7) … ) we need to find out the length of the shortest function that can be applied on A, B to get wanted array if no such function is possible then return -1. This is a very easy question but the language of the question was not clear.
- We are given a code sample and asked to optimize the code.
Given a string s of length n
Count = 0
for i =0 to n
for j = 0 to n
if( s[i] != s[j])
Count += abs(i-j)
