Given two strings, write a method to decide if one is a permutation of the other. Example Example 1:Input: "abcd", "bcad"Output: TrueExample 2:Input: "aac", "abc"Output: False 思路:count比较一下就可以;
Permutation Test 置换检验 显著性检验通常可以告诉我们一个观测值是否是有效的,例如检测两组样本均值差异的假设检验可以告诉我们这两组样本的均值是否相等(或者那个均值更大)。我们在实验中经常会因为各种问题(时间、经费、人力、物力)得到一些小样本结果,如果我们想知道这些小样本结果的总体是什么样子的,就需要用到置换检验。 Permutation test 置换检验是Fisher于2
