#154 - Find Minimum in Rotated Sorted Array II
Problem Description
Suppose an array of length n sorted in ascending order is rotated between 1 and n times.
For example, the array nums = [0,1,4,4,5,6,7] might become:
- [4,5,6,7,0,1,4] if it was rotated 4 times.
- [0,1,4,4,5,6,7] if it was rotated 7 times.
Notice that rotating an array [a[0], a[1], a[2], ..., a[n-1]] 1 time results in the array [a[n-1], a[0], a[1], a[2], ..., a[n-2]].
Given the sorted rotated array nums that may contain duplicates, return the minimum element of this array.
You must decrease the overall operation steps as much as possible.
Solution
/**
* @param {number[]} nums
* @return {number}
*/
var findMin = function(nums) {
for (let i = 0; i < nums.length - 1; i++) {
if (nums[i] > nums[i + 1]) {
return nums[i + 1];
}
}
return nums[0];
};
