For example, ball < cat, dog < dorm, Happy < happy, Zoo < ball. Constraints This is not done by simple combinatorics (I know the formulas and it doesn't work here). 1. Simple solution with expansion from an Index For each index we can try to expand as much as possible so that the substring is still palindromic. Function description Complete the diagonalDifference function in the editor below. Problem Solution. 4. I'm trying to solve the String Function Calculation problem from Hackerrank.
