这是一个套题,和416. Partition Equal Subset Sum,473. Matchsticks to Square基本一致的代码,上面的两个题分别是求平分成2份和4份。这个是任意的k份。所以改成了k组数字记录的div,最后看是否能够正好进行平分。
Partition Equal Subset Sum,473. Matchsticks to Square基本一致的代码,上面的两个题分别是求平分成2份和4份。这个是任意的k份。所以改成了k组数字记录的div,最后看是否能够正好进行平分。直接使用回溯法即可,这个回溯的要求是恰好把nums的所有数字用过一遍,使得目标数组中恰好有k个相同数字。当所有的数字恰好用完...
