题目
给定两个字符串 s1 和 s2,请编写一个程序,确定其中一个字符串的字符重新排列后,能否变成另一个字符串。
示例 1:
输入: s1 = "abc", s2 = "bca"
输出: true
示例 2:
输入: s1 = "abc", s2 = "bad"
输出: false
说明:
0 <= len(s1) <= 100
0 <= len(s2) <= 100
解题思路
遍历各数组1遍,O(n)
class Solution:
def CheckPermutation(self, s1: str, s2: str) -> bool:
aList = [i for i in s1]
for j in s2:
try:
aList.remove(j)
except:
return False
return True
