Maximum Gap Given an unsorted array, find the maximum difference between the successive elements in its sorted form. Try to solve it in linear time ...
梅西剛梅開二度,我也記一題。 在一個沒排序的數組里,找出排序后的相鄰數字的最大差值。 要求用線性時間和空間。 如果用nlgn的話,直接排序然后判斷就可以了。so easy View Code 但我們要的是線性時間。 其實這個思想在算法課上有講過。用桶的思想。把數組分成幾個桶,然后判斷相鄰桶的最大與最小之間的差值。關鍵是要知道每個桶的長度,已經桶的個數。 View Code 最后附上官網的解法說明: ...

前言 在比較排序的算法中,快速排序的性能最佳,時間復雜度是O(N*logN).因此,在使用比較排序時,時間復雜度的下限就是O(N*logN)。而桶排序的時間復雜度是O(N+C),因為它的實現並 ...
