For example, "dad" is a palindrome, as its reverse is "dad," whereas "program" isn't, as its reverse is "margorp" that is different from "program. Their absolute difference is |15 – 17| = 2. Function description Complete the diagonalDifference function in the editor below. Leaderboard. A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward or forward. Notice that when we start with building 1, we have no idea when the end of it's rectangle will be (represented by a dashed arrow going to the right). Start from the index (0,0) and print the elements diagonally upward then change the direction, change the column and print diagonally downwards. For example, the square matrix is shown below: The left-to-right diagonal =1 + 5 + 9 = 15.

But yes, when it comes to performances, storing data used only once is clearly ineffective. June 30, 2020 Array Reversal, Dynamic Array in C, HackerRank Solutions, Array Reversal - HackerRank Solution Given an array, of size , reverse it. Calculate the absolute difference of sums across the two diagonals of a square matrix. That being said, sometimes it may be better to write code that exhibits explicitly its logic, here "summing the elements of the diagonal of a square matrix" and for this purpose using a 2-D array could be better here I guess.
