题意:给定两个相同长度的字符串,让你找出一个字符串,字典序在两都之间. 析:这个题当时WA了好多次,后来才发现是这么水,我们只要把 s 串加上,然后和算数一样,该进位进位,然后再和 t 比较就行. 代码如下: #include <iostream> #include <cstdio> #include <algorithm> #include <vector> #include <set> #include <cstring> #in…

A. Vitaly and Strings 题意:两个字符串s,t,是否存在满足:s < r < t 的r字符串 字符转处理:字典序排序 很巧妙的方法,因为s < t,只要找比t字典序稍微小一点的和s比较就行了 具体方法和数字减1相类似,从"个位"减1,如果是0,从前面借1 !strcmp (t, s):如果t < s 或者 t > s (不可能)则输出,t == s 则输出NO #include <cstdio> #include <i…

Given two numbers represented as strings, return multiplication of the numbers as a string. Note: The numbers can be arbitrarily large and are non-negative. Converting the input string to integer is NOT allowed. You should NOT use internal library su…

Given two non-negative numbers num1 and num2 represented as string, return the sum of num1 and num2. Note: The length of both num1 and num2 is < 5100. Both num1 and num2 contains only digits 0-9. Both num1 and num2 does not contain any leading zero.…

Design an algorithm to encode a list of strings to a string. The encoded string is then sent over the network and is decoded back to the original list of strings. Machine 1 (sender) has the function: string encode(vector<string> strs) { // ... your…

Given a string, we can "shift" each of its letter to its successive letter, for example: "abc" -> "bcd". We can keep "shifting" which forms the sequence: "abc" -> "bcd" -> ... -> &quo…

Given two strings s and t, determine if they are isomorphic. Two strings are isomorphic if the characters in s can be replaced to get t. All occurrences of a character must be replaced with another character while preserving the order of characters.…

Given two numbers represented as strings, return multiplication of the numbers as a string. Note: The numbers can be arbitrarily large and are non-negative. 这道题让我们求两个字符串数字的相乘,输入的两个数和返回的数都是以字符串格式储存的,这样做的原因可能是这样可以计算超大数相乘,可以不受int或long的数值范围的约束,那么我们该如何来计算…

使用strings查看二进制文件中的字符串 今天介绍的这个小工具叫做strings,它实现功能很简单,就是找出文件内容中的可打印字符串.所谓可打印字符串的涵义是,它的组成部分都是可打印字符,并且以null或者newline结尾. 对于普通文本文件来说,strings没有任何意义,因为文本文件中的任何内容实际都是可打印的字符串.strings最常用的场合就是列出动态库或者可执行程序等二进制文件中出现的字符串,结合grep即可实现查找. strings的使用方法很简单,strings [文件]即可,…

1. Brief ES6(ECMAScript 6th edition)于2015年7月份发布,虽然各大浏览器仍未全面支持ES6,但我们可以在后端通过Node.js 0.12和io.js,而前端则通过Traceur或Babel这类Transpiler将ES6语法预转译为ES5语法,来提前兴奋一把.而仅需适配IE9+的朋友们现在更是可以开始撸ES6了,而不必为学哪门JavaScript超集语言而烦恼.(ES6又名为ECMAScript 2015或JavaScript.next,ES4的部分较为激进…

Hacking Strings The implementation of Redis strings is contained in sds.c ( sds stands for Simple Dynamic Strings ).The C structure sdshdr declared in sds.h represents a Redis string: struct sdshdr { long len; long free; char buf[]; }; The buf charac…

Write a method anagram(s,t) to decide if two strings are anagrams or not. 判断两个字符串里的字符是否相同,也就是是否能够通过改变字母顺序而变成相同的字符串. 如果是返回true,如果不是返回false. Clarification What is Anagram?- Two strings are anagram if they can be the same after change the order of chara…

[POJ3096]Surprising Strings 试题描述 The D-pairs of a string of letters are the ordered pairs of letters that are distance D from each other. A string is D-unique if all of its D-pairs are different. A string is surprising if it is D-unique for every pos…
