题意:如果两个字符串是对称的,就返回true.对称就是将串1中的同一字符都一起换掉,可以换成同串2一样的. 思路:ASCII码表哈希就行了.需要扫3次字符串,共3*n的计算量.复杂度O(n).从串左开始扫,若字符没有出现过,则赋予其一个特定编号,在哈希表中记录,并将该字符改成编号.对串2同样处理.其实扫2次就行了,但是为了短码. class Solution { public: void cal(string &s) { ]={}, cnt=; ; i<s.size(); i++) { if…

Question 205. Isomorphic Strings Solution 题目大意:判断两个字符串是否具有相同的结构 思路:构造一个map,存储每个字符的差,遍历字符串,判断两个两个字符串中相同位置字符的差是否相同 Java实现: public boolean isIsomorphic(String s, String t) { Map<String, Integer> map = new HashMap<>(); for (int i=0; i<s.length(…
