Hello everyone !!
I need to fill a matrix in a somewhat delicate way:
I have the number of columns and rows, but I need to fill it so that each column encodes its number in binary!!!
Basically, the matrix will contain only 1s and 0s...
If the number of columns = 5
and the number of rows = 3
the matrix would look like this:
1 0 1 0 1
0 1 1 0 0
0 0 0 1 1
HELP ME PLEASE !!
I’m waiting for you!!!
