Leetcode c语言-Longest Common Prefix Title: Write a function to find the longest common prefix string amongst an array of strings. 这道题目不难,唯一要注意的是二重指针的使用,因为给了一个字符串数组,也就是一个二维数组,strs[][],对于第一个字符串,应该是strs[0],对于第一个字符串中的第一个...
Algorithm to find a number that meets a gt (greater than condition) the fastest I have to check for the tipping point that a number causes a type of overflow. If we assume for example that the overflow number is 98, then a very inefficient way of doing that would be to start at 1....

I am sorry that I am still inable to give a personal explanation of the algorithm. I only read it from the two links above and mimic the code in the second link. You may use this code to solve the problemImplement strStr()on LeetCode. My accepted 4ms C++ code using KMP is as foll...
It is a super interesting problem - it's not about the algorithm SKILLs, it is about algorithm THINKING. In this problem, the goal is actually to have as less matched prefix as possible. Here is the thinking process: 1. How does KMP (prefix jump table calc.) work? It always starts ...

Sometimes it is hard to prepare tests for programming problems. Now Bob is preparing tests to new problem about strings — input data to his problem is one string. Bob has 3 wrong solutions to this problem. The first gives the wrong answer if the input data contains the substring s1, the...
