hey, can someone please help me with this problem? https://icpcarchive.ecs.baylor.edu/external/74/7401.pdf https://icpcarchive.ecs.baylor.edu/index.php?option=com_onlinejudge&Itemid=8&category=691&page=show_problem&problem=5423

You are given an infinite binary indexed tree, where each node's value is its index. You're also given two integers, N and K. you're supposed to print a walk on this tree, where each node you visit, you either add or subtract it to your sum. The length of the walk must be K and the final sum must be N.

thanks.
