Rotate Array@LeetCode Rotate Array 这题当然有很朴素的解法,例如利用k % nums.length次循环每次循环都将原字符串向右推移1位,或者直接计算出每个字符最终所应该在的位置直接进行赋值。 那么这两种方法,前者复杂度太高,或者不够清晰简单。 我选用的是在编程珠玑中提到的翻转方法,比如我们的输入是[1,2,3,4,5,...

[LeetCode] Rotate List Rotate List Given a list, rotate the list to the right by k places, where k is non-negative. For example: Given 1->2->3->4->5->NULL and k = 2, return 4->5->1->2->3->NULL. Time Complexity 计算LinkedList长度: O(N) O(N) + O(N) + O(N) = O...
在LeetCode 396题中,如何优化算法以提高效率? 问题: Given an array of integers A and let n to be its length. Assume Bk to be an array obtained by rotating the array A k positions clock-wise, we define a "rotation function" F on A as follow: F(k) = 0 * Bk[0] + 1 * Bk[1]...

但如果c在A中位置是倒数第三位那里,这时候的匹配就是成功的。 所以之前的做法就得在外面再加多个循环,一直迭代,直到搜索到能匹配的位置。 代码如下:(附详解) 代码语言:javascript 代码运行次数:0 运行 AI代码解释 boolrotateString(stringA,stringB){int i=0,j=0,s1=A.size(),s2=B.size();if(s1!=s2...
