原题链接:D.Interval Selection 题目大意: 给你一个长度为 n n n 的数组 a a a,定义一个区间 [ l , r ] [l,r] [l,r] 内的连续子数组为好的,当且仅当这个子数组内的所有元素 a l , a l + 1 , . . . , a r a_{l},a_{l+1},...,a_{r} al,al+1,...,ar 在当前区间中恰好
题目链接:点击打开链接 题目大意:给出一个n*n的矩阵的初始值,和最终的值,现在有m个操作 L i j ,将第i列的值重置为j,H i j,将第i行的值重置为j。问m个操作应该怎么执行,可以完成矩阵的变化。 从最终的值向前找寻方案,每次找行和列中剩余的颜色全部相同的,看是否存在没被使用的操作可以完成它,如果有就记录下来,那么最终按照记录的逆序输出,就是可以完成变化的序列啦 #includ
