HDU 1029 题目大意:给定数字n(n <= 999999 且n为奇数 )以及n个数,找出至少出现(n+1)/2次的数 解题思路:n个数遍历过去,可以用一个map(也可以用数组)记录每个数出现的次数, 若次数一旦达到(n+1)/2,即输出a[i] 注意能出现(n+1)/2次数的最多只有一个 /* HDU 1029 *Ignatius and the Princess IV --- dp */ #include <cstdio> #include <cstring> #in…

解题报告: 题目大意:就是要求输入的N个数里面出现的次数最多的数是哪一个,水题.暴力可过,定义一个一位数组,先用memset函数初始化,然后每次输入一个数就将下标对应的上标对应的那个数加一,最后将整个数组都扫一遍, 看哪一个最大就可以了. #include<cstdio> #include<cstring> ]; int main() { int N,d; while(scanf("%d",&N)!=EOF) { memset(times,,sizeof…

题目链接:hdu 1028 Ignatius and the Princess III 题意:对于给定的n,问有多少种组成方式 思路:dp[i][j],i表示要求的数,j表示组成i的最大值,最后答案是dp[i][i].那么dp[i][j]=dp[i][j-1]+dp[i-j][i-j],dp[i][j-1]是累加1到j-1的结果,dp[i-j][i-j]表示的就是最大为j,然后i-j有多少种表达方式啦.因为i-j可能大于j,这与我们定义的j为最大值矛盾,所以要去掉大于j的那些值 /*******…
