Two classic problems The following content requires a score higher than 188. You can already view it. 1. Given a bucket_size and a bucket_width, and a set of input numbers,

return the number of numbers in each bucket. 2. Perform linear interpolation to fill in missing points: Given a series of coordinate points (x1, y1), (x2, y2), ..., (xn, yn) , the spacing between some points is not as expected, indicating missing data. You need to fill in these missing points using a linear fitting method. (After finishing this, I had nothing to do and chatted with the interviewer for a long time. Please give me some points!)
