Can you solve this real interview question? Search in Rotated Sorted Array - There is an integer array nums sorted in ascending order (with distinct values). Prior to being passed to your function, nums is possibly rotated at an unknown pivot index k (1
FindHeaderBarSize There is an integer arraynumssorted in ascending order (withdistinctvalues). Prior to being passed to your function,numsispossibly rotatedat an unknown pivot indexk(1 <= k < nums.length) such that the resulting array is[nums[k], nums[k+1], ..., nums[n-1], nums[0...
这样处理之后,唯一可能还剩下的重复情况就是 nums[start] == nums[end],数组中其他所有元素都是不相等的。这时这两个相等的元素其实对我们最后的判断已经没有影响了,因为在前面我们已经考虑过 nums[start] == target 以及 nums[end] == target 的情况了,而我们的目的只是判断 nums 中是否有 target,所以不论...
题目地址:https://leetcode-cn.com/problems/search-in-a-sorted-array-of-unknown-size/题目描述Given an integer array sorted in ascending order, write a function to search target in nums. If target exists, then return its index, otherwise return -1. However, the array size is unknown to you...
