we pick a pivot element and then we partition the array into two halves, the one that has all elements smaller than it and the others that are larger than it. The good thing is that we know where the pivot index is. Thus, we can iteratively partition the half (and not the other hal...
Firstly, we will have an array B, B[i] = 1 if ith element not deleted yet, B[i] = 0 otherwise. We will build a Segment Tree whose each node has 1 value, it is the sum B[i] in [L, R]. Now, we can find the kth element in the array easily by binary search. Code: int...

做过Kth Smallest Element in a Sorted Matrix和Kth Smallest Number in Multiplication Table这两道题的同学应该对这种搜索方式并不陌生。核心思想是二分确定一个中间数,然后找到所有小于等于这个中间数的距离个数,用其跟k比较来确定折半的方向。具体的操作是,首先要给数组排序,二分搜索的起始 left 为0,结束位置 ...

Write a Python program to find the kth smallest element in a given binary search tree.Sample Solution: Python Code:class TreeNode(object): def __init__(self, x): self.val = x self.left = None self.right = None def kth_smallest(root, k): stack = [] while root or...
A distance function must be of the form function D2 = DISTFUN(ZI, ZJ), taking as arguments a 1-by-N vector ZI containing a single row of X or Y, an M2-by-N matrix ZJ containing multiple rows of X or Y, and returning an M2-by-1 vector of distances D2, whose Jth element is...
