题目描述:
Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand.
(i.e., [0,0,1,2,2,5,6] might become [2,5,6,0,0,1,2]).
You are given a target value to search. If found in the array return true, otherwise return false.
Example 1:
Input: nums = [2,5,6,0,0,1,2], target = 0
Output: true
Example 2:
Input: nums = [2,5,6,0,0,1,2], target = 3
Output: false
中文理解:
给定一个递增数组,按照其中某个元素旋转,得到两段递增有序拼接在一起的数组,判断某个给定值是不是在这个数组中。
解题思路:
直接遍历一遍,使用O(n)时间复杂度。
代码(java):
class Solution {
public boolean search(int[] nums, int target) {
for(int val:nums){
if(val==target)return true;
}
return false;
}
}
