// Multiply Matrices
// Given two square Matrices A[][] and B[][]. Your task is to complete the function multiply which stores the multiplied matrices in a new matrix C[][].
 
// Example 1:

// Input: 
// N = 2
// A[][] = {{7, 8}, {2 , 9}}
// B[][] = {{14, 5}, {5, 18}}

// Output: 
// C[][] = {{138, 179}, {73, 172}}
