public class KMPSubstringSearch { /* compute the prefix array for the pattern string */ private int[] prefixArray(String pattern) { int[] pre = new int[pattern.length()]; // pre[0] = 0, pre[i] means the index of prefix // index used to store the position of matched prefix int ...
该示例使用Java Stack容器构建反向字符串 char[] data = original.toCharArray(); First, we turn the string to an array of characters withtoCharArray. 首先,使用toCharArray将字符串转换为字符数组 Stack<Character> stack =newStack<>();for(charc: data) { stack.push(c); } In the second step, we ...

In this way, we can build up a boolean array dp[i][j] to record if S[i][j] is a palindrome. dp[i][j] = dp[i+1][j-1] && s[i] == s[j]. initilzation, dp[i][i] = true, one char is always a palindrome. fill up the matrix, this is a little bit tricky because ...
Follow up: Could you do it in O(n) time and O(1) space? 反转链表 复杂度 时间O(N) 空间 O(1) 思路 两个指针都从头出发,快指针每次两步,慢指针每次一步,这样快指针的下一个或下下个为空时,慢指针就在链表正中间那个节点了(如果链表有偶数个节点则在靠近头那侧的)。然后我们从慢指针的下一个...
