WebSuppose sum of ∑ i = 1 n a i = S (same as in editorial). If S is odd — obviously we can't. Also, by simplest pigeonhole principle we know if there is a i > S / 2, then we can't reduce all a i to zero. But, if there is a i > S / 2 it's easy to see that … WebApr 14, 2024 · P5427 [USACO19OPEN]Left Out bitset优化做01矩阵翻转; P5426 [USACO19OPEN]Balancing Inversions 枚举模拟; Sajam bitset进行01翻转 [USACO18JAN] Stamp Painting dp; CodeForces - 407C C - Curious Array 高阶差分序列 WebJan 2, 2024 · Practice.
