Codeforces Round #188 (Div. 1 + Div. 2)
A. Even Odds
- 奇数个数\(\lfloor \frac{n+1}{2}\rfloor\)
B. Strings of Power
- 从位置0开始,统计heavy个数,若当前为metal,则可以和之前的所有heavy配对。
C. Perfect Pair
- 假设\(x\le y\),显然用\(x+y\)替换\(x\)可以达到最少步数。
- \(x\)会一直\(+y\)直到\(x'\gt y\)。
D. Ants
- 暴力模拟???
E. Balance
- 构出一棵树后,就随便做了。
F. Game with Powers
- 考虑会相互影响的数,每组数的长度为\([1,29]\),对于每种长度的组暴力求出\(sg\)值。
- 计算每种长度的组数,需要重复计数问题,即长为\(L\)的组包含长\(l\lt L\)的组,需要扣除相应的重复长度。
