Question

Given an unsorted array, find the maximum difference between the successive elements in its sorted form.

Try to solve it in linear time/space.

Return 0 if the array contains less than 2 elements.

You may assume all elements in the array are non-negative integers and fit in the 32-bit signed integer range.

Solution

Result: Accepted Time: 16 ms

Here should be some explanations.

class Solution {
public:
    int maximumGap(vector<int>& nums) {
        int mx = 0;
        sort(nums.begin(),nums.end());
        for(int i = 1; i < nums.size(); i++)
            mx = max(mx,nums[i]-nums[i-1]);
        return mx;
    }
};
