题解:sliding window。(time complexity is O(N)) View Code 【161】One Edit Distance(2018年11月24日,刷题数) 给了两个字符串 s 和 t,问 s 能不能通过 增加一个字符, 删除一个字符,替换一个字符 这三种操作里面的任意一个变成 t。能的话返回 true, 不能的话返回 false。
Time complexity - O(log(N*M)) as we find the GCD of lengths and concatenate the string Space complexity - O(N + M), as we required to store the shortest string. The solution to the problem was very similar to the finding LCM of two numbers, but we need to make...
We investigate the space–time picture of string evolution and hadron production in a fully string-based model for high energy collisions involving heavy-ions. We find that although the density of strings is quite large at the time of hadronization in a central heavy-ion collision, the initial ...
The idea is to find a linear time algorithm. 0 votes Bhavesh Kumar 10 years ago Thank you , I am not much good at Time Complexity Topic but I guess this one is linear #include<iostream>using namespace std ; int main(){ string S = "acatataaataatyuytatataaataattaaata" ; string...
