To reverse a string "in place" without using a temporary string, use the reverse function template in the <algorithm> header: Demo Code#include <string> #include <iostream> using namespace std; int main() {// w w w . ja v a 2s .co m string s = "this is a test"; cout <<...
Skip to content Life in USA About Admin My Apps Tag: algorithm KMP 算法 KMP算法用于字符串的模式匹配,也就是查找某个字符串里是否存在某个子串,并返回位置,也就是Java/C++里的String.indexOf()方法。 字符串匹配最朴素的算法就是一个一个去比较,出错了就回溯到下一个起点继续比较。这样的复杂度有O...

To reverse a string A string can be reversed by using stack. The characters of string pushed on to the stack till the end of the string. The characters are popped and displays. Since the end character of string is pushed at the last, it will be printed first. ...

StringEncrypt allows you to encrypt strings and files using a randomly generated algorithm, generating a unique decryption code (so-called polymorphic code) each time in the selected programming language. - PELock/StringEncrypt-Python
To reverse the order, you can use rbegin() and rend() instead of begin() and end():Example // Create a vector called numbers that will store integersvector<int> numbers = {1, 7, 3, 5, 9, 2};// Sort numbers numerically in reverse ordersort(numbers.rbegin(), numbers.rend()); ...
