import numpy as np    b = np.array([12, 90, 380, 12, 211])    print(np.where(b>12))    c = np.array([[20, 24],[21, 23]])    print(np.where(c>20))  Output:(array([1, 2, 4]),)(array([0, 1, 1]), array([1, 0, 1]))

The code you provided is written in Python, specifically using the numpy library.

The np.where() function is used to check the condition specified and return the indices where the condition is true.

In the first part of the code, np.where(b>12) is checking for the indices in array b where the value is greater than 12. The output (array([1, 2, 4]),) means that the values at indices 1, 2, and 4 in array b are greater than 12.

In the second part of the code, np.where(c>20) is checking for the indices in array c where the value is greater than 20. The output (array([0, 1, 1]), array([1, 0, 1])) is a tuple of two arrays. The first array represents the row indices and the second array represents the column indices. So, the values greater than 20 in array c are at positions (0,1), (1,0), and (1,1).
