+
+1. 利用 ba=(br)^T(ar)^T=(arbr)^T，通过三次反转字符串: 即首先对序列前部分逆序，再对序列后部分逆序，再对整个序列全部逆序
+
+2. 分组交换(尽可能使数组的前面连续几个数为所要结果):a长度大于b，将 ab 分成 a0a1b，交换 a0 和 b，得 ba1a0，只需再交换 a1和 a0。若 a 长度小于 b，将 ab 分成 ab0b1，交换 a 和 b0，得 b0ab1，只需再交换 a 和b0。通过不断将数组划分，和交换，直到不能再划分为止。分组过程与求最大公约数很相似。
+
+3.所有序号为 (j+i*m) % n (j 表示每个循环链起始位置，i 为计数变量，m 表示左旋转位数，n 表示字符串长度)，会构成一个循环链（共有 gcd(n,m)个，gcd 为 n、m 的最大公约数），每个循环链上的元素只要移动一个位置即可，最后整个过程总共交换了 n 次（每一次循环链，是交换 n/gcd(n,m)次，总共 gcd(n,m)个循环链。所以，总共交换 n 次）。
