这道题是LeetCode里的第6道题. 题目要求: 将一个给定字符串根据给定的行数,以从上往下.从左到右进行 Z 字形排列. 比如输入字符串为 "LEETCODEISHIRING" 行数为 3 时,排列如下: L C I R E T O E S I I G E D H N 之后,你的输出需要从左往右逐行读取,产生出一个新的字符串,比如:"LCIRETOESIIGEDHN". 请你实现这个将字符串进行指定行数变换的函数: string convert(string s…

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)…

题目: 把一个字符串按照Z型排列后打印出来,例如 "PAYPALISHIRING" 重新排列后为3行,即 P A H N A P L S I I G Y I R 那么输出为"PAHNAPLSIIGYIR" 解法: 细节实现题,假如重新排列为5行,那么排列后的下标分布应该为 0  8   16 24 1 7 9   15   17 23 2 6 10 14 18 22 3 5 11 13 19 21 4  12 20 可以看出规律,输出为5行的时候,每两个完整列之间的…

问题:给定 n 行和 m 列的二维数组矩阵.如图所示,以 ZIG-ZAG 方式打印此矩阵. 从对称的角度来看,通过反复施加滑行反射可以从简单的图案如线段产生规则的之字形. 主要思想:算法从(0, 0)位置开始水平向右遍历,当到达(0, 1)时沿着反对角线方向左下遍历(利用一个变量控制左下右上方向),内层循环一直遍历到碰到边缘时row++,方向改为右上,沿着反对角线碰到矩阵上边缘时col++,方向变为左下遍历,知道上半部分(包括反对角线遍历完):遍历完半个矩阵(可能是子方矩阵)后,根据当前 row…
