//Implement an algorithm to determine if a string has all unique characters What if //you can not use additional data structures? #include #include using namespace std; //适合所有ascii字符 bool uniquech

//Design an algorithm and write code to remove the duplicate characters in a string //without using any additional buffer NOTE: One or two additional variables are fine // An extra copy of the array

排序年龄的算法 //复杂度为On的排序算法 #include #include using namespace std; const int oldestage=99; void OnSort(vector &v1) { if(v1.size()==0)return; vector v2(oldestage+1,0); for (auto i =0;i<v1.size();i++)

//倒置字符串 #include using namespace std; //倒置原字符串 void reverse1(char * s) { if (s) { char temp; char * end=s; while (*end)//记住这里end只表示一个字符 { end++; } --end; while (s<end) { temp

面试题是我找的，代码也看了，但是代码我自己写的！！！
