[抄题]: Given two strings s and t which consist of only lowercase letters. String t is generated by random shuffling string s and then add one more letter at a random position. Find the letter that was added in t. Example: Input: s = "abcd" t = &q

目的:找出一个整形数组中的元素的最大值 以下,我们用类和对象的方法来做. #include<iostream> using namespace std; class Array_max{ private://声明在类的外部不可訪问的隐私成员 int array[10]; int max; public://声明在类的外部能够訪问的开放的成员函数 void set_value(){ int i; cout<<"请输入10个整数"<<endl;
在实际的nlp实际任务中,你有一大堆的人工标注的关键词,来新的一句话,找出这句话中的关键词,以便你以后使用,那如何来做呢? 1)用到正则的 finditer()方法,返回你匹配的关键词的迭代对象,包含起始结束索引 2)增强list循环,提取数据 代码如下: import re s = 'dengyexun' idx = [i.start() for i in re.finditer('y', s)] 这里我只要开始索引,结果如下: 之后,你想怎么用都可以的

Given an array of integers where 1 ≤ a[i] ≤ n (n = size of array), some elements appear twice and others appear once. Find all the elements of [1, n] inclusive that do not appear in this array. Could you do it without extra space and in O(n) runtime?

Given two words (start and end), and a dictionary, find all shortest transformation sequence(s) from start to end, such that: Only one letter can be changed at a time Each intermediate word must exist in the dictionary For example, Given:start ="hit&
题目: There are two sorted arrays nums1 and nums2 of size m and n respectively. Find the median of the two sorted arrays. The overall run time complexity should be O(log (m+n)). 题意: 两个排序后的数组nums1 和nums2,长度分别是m,n,找出其中位数,并且时间复杂度:O(log(m+n)) 最愚蠢的方法: 两个数组合
