{"library":"Numpy","prompt":"Problem:\nI have two numpy arrays x and y\nSuppose x = [0, 1, 1, 1, 3, 1, 5, 5, 5] and y = [0, 2, 3, 4, 2, 4, 3, 4, 5]\nThe length of both arrays is the same and the coordinate pair I am looking for definitely exists in the array.\nHow can I find indices of (a, b) in these arrays, where a is an element in x and b is the corresponding element in y.I want to take an increasing array of such indices(integers) that satisfy the requirement, and an empty array if there is no such index. For example, the indices of (1, 4) would be [3, 5]: the elements at index 3(and 5) of x and y are 1 and 4 respectively.\nA:\n<code>\nimport numpy as np\nx = np.array([0, 1, 1, 1, 3, 1, 5, 5, 5])\ny = np.array([0, 2, 3, 4, 2, 4, 3, 4, 5])\na = 1\nb = 4\n</code>\nresult = ... # put solution in this variable\nBEGIN SOLUTION\n<code>\n"}
