I need some problems on Exchange arguments technique.
By _Tyrue_, history, 6 weeks ago, In English

Problems from AtCoder and Codeforces are both fine, preferably those where the 'Exchange arguments' method is used to optimize greedy algorithms.

Thanks~

Exchange arguments is not an optimisation technique? It's a proving method not an algorithm or technique. In any case, a problem which can be proved using this method. https://codeforces.me/problemset/problem/632/C
