JSU省赛队员选拔赛个人赛1 一.题目概述: A.Coin Change(暴力求解.动态规划)     B.Fibbonacci Number(递推求解) C.Max Num(排序.比较) D.单词数(字符串比较.库函数运用) E.无限的路(平面几何) F.叠筐(规律输出) 二.解题报告: A.Coin Change 给一个钱的总金额,求出用100个以内的50分.25分.10分.5分.1分硬币拼成该金额的不同拼法. 直接暴力,打表什么的都是浮云.开始总觉得用暴力求解显得自己没风度,不够高端霸气上…

因为是circle sequence,可以在序列最后+序列前n项(或前k项);利用前缀和思想,预处理出前i个数的和为sum[i],则i~j的和就为sum[j]-sum[i-1],对于每个j,取最小的sum[i-1],这就转成一道单调队列了,维护k个数的最小值. ---------------------------------------------------------------------------------- #include<cstdio> #include<deque&…

题目传送门 题意:求MCS(最大连续子序列和)及两个端点分析:第一种办法:dp[i] = max (dp[i-1] + a[i], a[i]) 可以不开数组,用一个sum表示前i个数字的MCS,其实是一样的...类似DP的做法有个名字叫联机算法. 第二种办法:一个前缀记录前i个数字的和,那么ans = sum - mn; mn表示前j个和且和最小 两种办法都是O (n) 1003就这么难?? 推荐学习资料:六种姿势拿下连续子序列最大和问题 最大子序列和问题 收获:MCS问题的两种o (n) 的算…

写的第一个版本,使用穷举(暴力)的方法,时间复杂度是O(N^2),执行时间超过限制,代码如下: #include <stdio.h> #define MAX_LEN 100000UL int max_subsequence(int *array, unsigned int len, unsigned int *start, unsigned int *end) { ], sum; ; *start = *end = ; while(t_start < len){ sum = ; for…

Problem Description Given a sequence a[1],a[2],a[3]......a[n], your job is to calculate the max sum of a sub-sequence. For example, given (6,-1,5,4,-7), the max sum in this sequence is 6 + (-1) + 5 + 4 = 14. Input The first line of the input contains…
