关于快慢指针的理解
2022-07-17 06:56:00 【白速龙王的回眸】
low = fast 时,快慢指针相遇,low 走过的距离是初始点(0)到环状开始的点 (x) 加上 环状开始的点(x) 到相遇点(y) 这段距离,而fast走过的距离是 初始点(0)到环状开始的点(x),点(x) 到点(y),点(y)到点(x),点(x)到点(y)。又因为fast走过的距离是low的两倍,设0到x长度为a,x到y长度为b,则有2*(a+b) = a+ b+ (y到x的距离) + b,则y到x的距离就等于0到x的距离。所以当新的两个指针 一个从0出发,一个从相遇点y出发时,他们走到的相同的值就是环状开始的点,即x点。
