You are given an array of positive and negative integers. If a number n at an index is positive, then move forward n steps. Conversely, if it's negative (-n), move backward n steps. Assume the first element of the array is forward next to the last el…
You are given a circular array nums of positive and negative integers. If a number k at an index is positive, then move forward k steps. Conversely, if it's negative (-k), move backward k steps. Since the array is circular, you may assume that the la…

环形数组循环 给定一组含有正整数和负整数的数组.如果某个索引中的 n 是正数的,则向前移动 n 个索引.相反,如果是负数(-n),则向后移动 n 个索引. 假设数组首尾相接.判断数组中是否有环.环中至少包含 2 个元素.环中的元素一律"向前"或者一律"向后". 示例 1:给定数组 [2, -1, 1, 2, 2], 有一个循环,从索引 0 -> 2 -> 3 -> 0. 示例 2:给定数组[-1, 2], 没有循环. 注意:给定数组保证不包含元素&…
457. 环形数组循环 给定一个含有正整数和负整数的环形数组 nums. 如果某个索引中的数 k 为正数,则向前移动 k 个索引.相反,如果是负数 (-k),则向后移动 k 个索引.因为数组是环形的,所以可以假设最后一个元素的下一个元素是第一个元素,而第一个元素的前一个元素是最后一个元素. 确定 nums 中是否存在循环(或周期).循环必须在相同的索引处开始和结束并且循环长度 > 1.此外,一个循环中的所有运动都必须沿着同一方向进行.换句话说,一个循环中不能同时包括向前的运动和向后的运动. 示例…

Design your implementation of the circular double-ended queue (deque). Your implementation should support following operations: MyCircularDeque(k): Constructor, set the size of the deque to be k. insertFront(): Adds an item at the front of Deque. Ret…
Design your implementation of the circular queue. The circular queue is a linear data structure in which the operations are performed based on FIFO (First In First Out) principle and the last position is connected back to the first position to make a…
