在写代码中经常会遇到需要在数组循环中删除数组元素的情况,但删除会导致数组长度变化. package com.fortunedr.thirdReport; import java.util.ArrayList; import java.util.List; public class Test { public static void main(String[] args) { // TODO Auto-generated method stub List<String> list=new Arr
这一段程序 下面这段程序很有看点://arr1 is an array of intsint *source=arr1;size_t sz=sizeof(arr1)/sizeof(*arr1);//number of elementsint *dest=new int[sz];while(source!=arr1+sz) *dest++=*source++;//copy element and increment pointers 1.source是一个指向数组arr1的第一个元素的指针.
HDU1004 思路:求数组中出现次数最多的那个元素: 遍历数组元素,找出每个元素出现的次数 Input Input contains multiple test cases. Each test case starts with a number N (0 < N <= 1000) -- the total number of balloons distributed. The next N lines contain one color each. The color of a ballo
