Largest Number At Least Twice of Others
You are given an integer array nums where the largest integer is unique.
Determine whether the largest element in the array is at least twice as much as every other number in the array. If it is, return the index of the largest element, or return -1 otherwise.
Example 1
Input
nums = [3,6,1,0]Output
16 is the largest integer, it is at least twice as big as every other number, and its index is 1.Example 2
Input
nums = [1,2,3,4]Output
-14 is less than twice the value of 3, so return -1.Constraints
- 2 <= nums.length <= 50
- 0 <= nums[i] <= 100
- The largest element in nums is unique.
