Fellow programmers, Someone please explain Problem C (Change ABC string with k swaps), and Problem D (maximum number of times operations can chnage state of white squares to black). I went through editorial, solution of other people I didnot understand. Please explain it. Thanks.

And also how to practice nim game problems, it took me alot of time to solve problem B, good problem suggestions to understand the nim theory or grundy numbers? Thanks again.
