Implement largestDiff(arr) by sorting the array ascending and subtracting the first element from the last. Return 0 for arrays with fewer than two elements.
Examples
Example 1:
Input: largestDiff([2, 24, 7, 4, 13, 6, 30, 8])
Output: 28
Explanation: after sorting the smallest is 2 and the largest is 30, so the maximum difference is 30 - 2 = 28.4 more questions, with full solutions and explanations, are available for premium members.
