Given an array of integers, calculate the fractions of its elements that are positive, negative, and are zeros. Print the decimal value of each fraction on a new line.

Given a square matrix, calculate the absolute difference between the sums of its diagonals.

For example, the square matrix is shown below:

1
2
3

1 2 3
4 5 6
9 8 9

The left-to-right diagonal = 1 + 5 + 9 = 15. The right to left diagonal = 3 + 5 + 9 = 17. Their absolute difference is |15 - 17| = 2.

Calculate and print the sum of the elements in an array, keeping in mind that some of those integers may be quite large.

Alice and Bob each created one problem for HackerRank. A reviewer rates the two challenges, awarding points on a scale from 1 to 100 for three categories: problem clarity, originality, and difficulty.

We define the rating for Alice’s challenge to be the triplet a = (a[0], a[1], a[2]), and the rating for Bob’s challenge to be the triplet b = (b[0], b[1], b[2]).

Your task is to find their comparison points by comparing a[0] with b[0], a[1] with b[1], and a[2] with b[2].
