the answer is supposed to be [1,2] or [2,1] but my code is giving [0,0]

can someone help me please?

4. (15) Given Numpy arrays A1 and A2 of shapes ($111.11) and {mam} inter- pret their rows as points in n-dimensional space. Note that these arrays have the same number of columns. Dene a function closestoint which will take as input two Numpy arrays A1 and A2 as described above and will return the index of the row from 151.1 which is closest to a row in A2. Note that It may vary as arrays of any size can be passed to this function. The only restriction is that they must have the same number of columns. You may only use Numpy functionality, no other modules are allowed in this problem. You also may not use loops
