The Art of Word Shaping
Given a binary matrix and a string of letters, replace all 1's in the matrix, moving from top to bottom and from left to right within each row, with the letters of the string. Once the letters have been formed into the shape of the matrix, print the matrix, replacing 0's with spaces. It's probably easier to just give an example or two.
Case: Base case...
[0,0,1,0,0] [0,1,0,1,0] [1,0,0,0,1] [0,1,0,1,0] [0,0,1,0,0] "PPCGPPCG"
P P C G P P C G
Case: If the input string is longer than the number of ones...
[1,0,0] [0,1,0] [1,0,1] lambda
l a m b
Case: If the input string is shorter than the number of ones...
[1,1,1] [1,0,1] [1,1,1] PPCG
PPC G P PCG
- You may assume the input string is never empty.
- You may assume the matrix will never be empty.
- You may not assume that the binary matrix will never be all zeros.
- If the string is shorter than the number of ones, repeat the string; all ones must be replaced.
- If the string is longer than the number of ones, only use what is needed.
- You may use True/False in place of integers/bits for the input.
- Trailing spaces ARE REQUIRED, all zeros must be replaced with spaces.
- A single trailing newline is acceptable.
- This is code-golf, lowest byte count wins.
