Hi, I need to generate all variants of a 2D array with variable dimension sizes which fit a specific rule. (up to 200*1000)
The rules are: - Values are only 0 or 1 - the sum of each line bust be 1 - only valid results must be generated (generating all and only returning the valid results takes to long; that's what I tried already) So for a 2x2 array these would be the valid results: 10 01 01 10 10 10 01 01 Must be possible with nested loops and a counter per line. But I don't get it. Can someone help? Thanks Robert -- https://mail.python.org/mailman/listinfo/python-list
