This is how one might implement such a solution in python: implementation Unfortunately, this works in O(n2)O(n2) time. How can we optimize this? We can use dynamic programming. For a 11-indexed array-like data structure AA of length nn, let's define dpidpi as the minimum element that...
Find the minimum element. You may assume no duplicate exists in the array. 这是LeetCode 上的一道算法题,题意是一个已经排序的数组,截断后重新拼接,找出数组中最小的数字。 这道题目用 Python 来实现的话太简单了。代码如下: classSolution:#@param num, a list of integer#@return an integerdeffindMin...
As said above, if there are multiple occurrences of a single element, theindex()method only returns the leftmost index of the element. If we would have passed element 1 as the input argument to theindex()method, the output would have been 3 despite the fact that element 1 is also presen...
Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e.,0 1 2 4 5 6 7might become4 5 6 7 0 1 2). Find the minimum element. You may assume no duplicate exists in the array. 代码:oj测试通过 Runtime: 52 ms 1classSolution:2#@param num, a list of in...
