1. Linked List Cycle II Given a linked list, return the node where the cycle begins. If there is no cycle, return null. Note: Do not modify the linked list. 思路:想法是利用两指针,一个每次移动一步,另一个每次移动两步,如果存在环则这两个指针一定会相遇(这里可以在纸上画一下,因为后一个指针移动比前一个指针快,当后一个指针在环中来到前一个指针的…

分数转小数,要求输出循环小数 如2 3 输出0.(6) 弗洛伊德判环的原理是在一个圈里,如果一个人的速度是另一个人的两倍,那个人就能追上另一个人.代码中one就是速度1的人,而two就是速度为2的人. Fraction to Recurring Decimal可以使用弗洛伊德判环,不同的是要找到循环出现的起始点,因此会比单单判断是否循环出现的题要难一点,代码要长一点,但是它比是用map的实现会更快. 要做出这道题有几个注意点: 1)对于整数的求余和整除运算要注意,特别负数的求余运算, 可以参考…
