2016. Maximum Difference Between Increasing Elements

Easy

Array

Problem Explanation

Explanation

To find the maximum difference between increasing elements in the array, we can iterate through the array and keep track of the minimum element seen so far. For each element, we calculate the difference between the current element and the minimum element, and update the maximum difference if needed.

Initialize maxDiff as -1 to indicate no valid difference found yet.
Initialize minElement as the maximum value possible.
Iterate through the array and update minElement and maxDiff accordingly.
Return the maxDiff as the final result.

Time Complexity: O(n)
Space Complexity: O(1)

Solution Code

class Solution {
    public int maximumDifference(int[] nums) {
        int maxDiff = -1;
        int minElement = Integer.MAX_VALUE;
        
        for (int num : nums) {
            if (num > minElement) {
                maxDiff = Math.max(maxDiff, num - minElement);
            }
            minElement = Math.min(minElement, num);
        }
        
        return maxDiff;
    }
}
