[LintCode] Maximum Gap 求最大间距
Given an unsorted array, find the maximum difference between the successive elements in its sorted form.
Return 0 if the array contains less than 2 elements.
Notice
You may assume all elements in the array are non-negative integers and fit in the 32-bit signed integer range.
Have you met this question in a real interview?
Yes
Example
Given [1, 9, 2, 5]
, the sorted form of it is[1, 2, 5, 9]
, the maximum gap is between 5
and 9
= 4
.
Challenge
Sort is easy but will cost O(nlogn) time. Try to solve it in linear time and space.
