{"library":"Numpy","prompt":"Problem:\nI have two arrays A (len of 3.8million) and B (len of 20k). For the minimal example, lets take this case:\nA = np.array([1,1,2,3,3,3,4,5,6,7,8,8])\nB = np.array([1,2,8])\nNow I want the resulting array to be:\nC = np.array([1,1,2,8,8])\ni.e. if any value in A is not found in B, remove it from A, otherwise keep it.\nI would like to know if there is any way to do it without a for loop because it is a lengthy array and so it takes long time to loop.\nA:\n<code>\nimport numpy as np\nA = np.array([1,1,2,3,3,3,4,5,6,7,8,8])\nB = np.array([1,2,8])\n</code>\nC = ... # put solution in this variable\nBEGIN SOLUTION\n<code>\n"}
