1.什么是T test? t-test:比较数据的均值,告诉你这两者之间是否相同,并给出这种不同的显著性(即是否是因为偶然导致的不同) The t test (also called Student’s T Test) compares two averages (means) and tells you if they are different from each other. The t test also tells you how significant the differences…

Given an integer array of N integers, find the sum of bit differences in all the pairs that can be formed from array elements. Bit difference of a pair (x, y) is the count of different bits at the same positions in binary representations of x and y.…

About this Course This course will teach you how to build convolutional neural networks and apply it to image data. Thanks to deep learning, computer vision is working far better than just two years ago, and this is enabling numerous exciting applica…

You are given an integer array nums and you have to return a new counts array. The counts array has the property where counts[i] is the number of smaller elements to the right of nums[i]. Example: Given nums = [5, 2, 6, 1] To the right of 5 there are…
