Problem 2045. Only once: cleaning up your columns
We have a logical array (with ones and zeroes). It is simple: after processing every column may only contain a single true value, or none at all. Not on any row, but only the uppermost occurrence in the input array, if any.
For example:
[ 0 0 1 1
0 1 0 1
0 0 1 1 ] becomes [ 0 0 1 1
0 1 0 0
0 0 0 0 ]
And of course, your solution should be the most innovative, shortest and most elegant one.
