(大不了一个字母算一个子串) Given this observation it is natural to ask: what is the minimum number of groups needed for a given string such that every group is a palindrome? For example: • ‘racecar’ is already a palindrome, therefore it can be partitioned into one group. • ‘...
【题解】UVA11584 Partitioning by Palindromes UVA11584https://www.luogu.org/problemnew/show/UVA11584暑假开始刷lrj紫/蓝书DP题这几天做的一道思路预处理出所有的回文串是否存在 前提 如果是j~i是回文串 方程f[i]=min(f[i],f[j-1]+1);代码View Code分类: 题库---Uva , 动态规划---线性DP 好文...
bool ok[N][N]; string str; int main() { int t; scanf("%d", &t); while (t--) { cin >> str; memset(dp, inf, sizeof(dp)); memset(ok, 0, sizeof(ok)); int n = str.length(); for (int i = 0; i < n; ++i) { ok[i][i] = 1; } for (int i = n - 2; i...

'racecar' is already a palindrome, therefore it can be partitioned into one group. 'fastcar' does not contain any non-trivial palindromes, so it must be partitioned as ('f', 'a', 's', 't', 'c', 'a', 'r'). 'aaadbccb' can be partitioned as ('aaa', 'd', 'bccb'). ...
For each test case, output a line containing the minimum number of groups required to partition the input into groups of palindromes. Sample Input 3 racecar fastcar aaadbccb Sample Output 1 7 3 解题思路:题目大意:给定一个由小写字母组成的字符串,你的任务是把它划分成尽量少的回文串,字符串长度...
Input begins with the numbernof test cases. Each test case consists of a single line of between 1 and 1000 lowercase letters, with no whitespace within. For each test case, output a line containing the minimum number of groups required to partition the input into groups of palindromes. ...
