这个题的要求是给你一个字符串,和一个行数,例如(s = "mysisteristhemostlovelygirl" , row = 4),每一行一个字符串,但是s却得按照zigzag的方式重排序到这4行的字符串里,什么意思呢? 看例子大概就懂了: m e e   o   i y t r h m l v g r s s i t o t e y l i   s s   l 第一列开始往下走,走到第四行就往上走(第二列),走回第一行就重新往下走,如此类推,最后的输出就是每一行的叠加,也就是:…
题目: 思路: 以图为例:s={'A','B','C','D','E','F','G','H'.....} 1.先不考虑中间元素F.G.H.N...,每一行前后元素在数组中对应下标相差size=2*numRows-2(其中numRows是行数) 例如:第1行起始元素s[0]=A,在不大于数组长度情况下,size=2*5-2=8,该行往后依次是s[0+8]=s[8],s[0+8+8]=s[16]..... 2.考虑加入中间元素,j表示当前元素所在数组的下标,i为该元素所在行(从0开始),则除第一行…

ZigZag Conversion 看了三遍题目才懂,都有点怀疑自己是不是够聪明... 就是排成这个样子啦,然后从左往右逐行读取返回. 这题看起来很简单,做起来,应该也很简单. 通过位置计算行数: P I N A L S I G Y A H R P I 0,0 1,1 2,2 3,3 4,2 5,1 6,0 (期望) 用简单的先思考: P A H N A P L S I I G Y I R 0,0 1,1 2,2 3,3 4,0 %4 (3+1)可以解决正常的 3,1(期望) 特殊的3(2行2排…

Question 6. ZigZag Conversion Solution 题目大意:将字符串按Z字型排列,然后再一行一行按字符输出 思路:按题目中的第一个例子,画出如下图,通过n的不同值,可以找出规律红线的长度是2*n-2,蓝线的长度是interval - row,这样根据已知参数知道有n行,所以遍历n行,每行有多少列呢,每一列最后一列必须小于s.length,这样就可以通过遍历来求出最终结果了. Java实现: public String convert(String s, int n)…
乘风破浪:LeetCode真题_006_ZigZag Conversion 一.前言 到这里我们对基本的问题有了一定的理解,其中字符串的操作一直是一个比较困难的问题,这一点我们需要认真对待,采用合理的方案去解决问题.下面我们就看看将字符串按照某种格式排列之后再按行输出的问题. 二.ZigZag Conversion 2.1 问题理解 2.2 分析以解决问题     看到这样的问题我们最直接的想法就是构造一个二维数组,初始化成某种字符,然后按照题目给定的规则进行填充,填充完成之后按行进行遍历,将结…
