Given a matrix of integers A of size N x M and an integer B.
In a single operation, B can be added to or subtracted from any element of the matrix.
Find and return the minimum number of operations required to make all the elements of the matrix equal and
if it impossible return -1 instead.
Note: Rows are numbered from top to bottom and columns are numbered from left to right.
The first argument given is the integer matrix A. The second argument given is the integer B.
Return the minimum number of operations required to make all the elements of the matrix equal and if it impossible return -1 instead.
1 <= N, M <= 1000 -1000 <= A[i] <= 1000 1 <= B <= 1000
Input 1: A = [ [0, 2, 8] [8, 2, 0] [0, 2, 8] ] B = 2 Output 1: 12 Input 2: A = [ [5, 17, 100, 11] [0, 0, 2, 8] ] B = 3 Output 2: -1
NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a doubt? Checkout Sample Codes for more details.
