Description You are given a sequence of integers, A = a1, a2, ... an. A consecutive subsequence of A (say ai, ai+1 ... aj) is called a "repeated sequence" if it appears more than once in A (there exists some positive k that ai+k = ai, ai+k+1 = a…
时间限制:2000ms 单点时限:200ms 内存限制:256MB 描写叙述 Given N arithmetic expressions, can you tell whose result is closest to 9? 输入 Line 1: N (1 <= N <= 50000). Line 2..N+1: Each line contains an expression in the format of "a op b" where a, b are intege…
动态规划基本题目,longest incresing sequence,找出序列中的最长递增子序列: 例如给出序列{8,3,5,2,4,9,7,11}, 其中最长递增子序列为{3,5,9,11}或{3,5,7,11}或{3,4,9,11}或{3,4,7,11},子序列按元素递增,序列长度都为4: 子问题:第i处的最长子序列问题 定义问题: 阶段:后序,到第i项为阶段i: 状态:到i处的最长子序列为dp[i]: 决策:dp[i]=max{dp[j]}+1,i<j<=n,a[i]<a[j]…

题目如下: Given a string text, we are allowed to swap two of the characters in the string. Find the length of the longest substring with repeated characters. Example 1: Input: text = "ababa" Output: 3 Explanation: We can swap the first 'b' with the…
Programming pearls 编程珠玑的题目 这段时间有空都在看编程珠玑,很经典的一本书,一边看一边用 python 做上面的题目,我做的都放到 github 上了 https://github.com/fengyc/programming-pearls-2nd-python. 编程珠玑这书有段历史了,上面有些概念估计现在的学生听都没有听过,像磁带排序.3n+1问题等估计有些人听都没有听过,我花了点时间把相应的东西整理了,性能估算部分是根据现在的计算机速度重新估算了,还挺有意思的. 推荐…
题目:C++编程显示四则运算题目 设计思路:(1)让用户自己确定出题的数量,同时显示加减乘除四则运算. (2)考虑到用户可能只会一种运算,因此可以选择运算.…
