{"library":"Numpy","prompt":"Problem:\nLet's say I have a 2d numpy integer array like this\na = array([[1,0,3], [2,4,1]])\nI would like to encode this as a 2D one-hot array(in C order, e.g., a[1,1] corresponds to b[4]) for integers.\nb = array([[0,1,0,0,0], [1,0,0,0,0], [0,0,0,1,0], [0,0,1,0,0], [0,0,0,0,1], [0,1,0,0,0]])\nThe leftmost element always corresponds to the smallest element in `a`, and the rightmost vice versa.\nIs there a quick way to do this only using numpy? Quicker than just looping over a to set elements of b, that is.\nA:\n<code>\nimport numpy as np\na = np.array([[1,0,3], [2,4,1]])\n</code>\nb = ... # put solution in this variable\nBEGIN SOLUTION\n<code>\n"}
