Match lists based on the closest value

I have two lists:

a = [35, 400, 200]
b = [100, 32]

I want to match each value in ‘b’ with the closest value in ‘a’. Each value in ‘b’ can have at most one match. The final list contains values that are in list ’a’. So, in this case 35 is closest to 32 and 200 is closest to 100. Therefore, list that I want to get is

c = [35, 200]

I am able to solve this with a for loop, however I am looking for a vectorized solution.

You should also post your for loop solution. – WhySoSerious Aug 14 '23 at 14:30

@WhySoSerious That link is highly relevant. This question is basically a duplicate of it. The answer https://stackoverflow.com/a/46184652/4996248 seems to be just what OP is searching for. – John Coleman Aug 14 '23 at 14:39
