For example, say m = 4. Now 15 = 1111 in binary and so the output should be (1,1,1,1). 2 = 10 in binary and so the output should be (0,0,1,0). If m were 3 then 2 should be converted to (0,1,0).\\nI tried np.unpackbits(np.uint8(num)) but that doesn't give an array of the right length. For example,\\nnp.unpackbits(np.uint8(15))\\nOut[5]: array([0, 0, 0, 0, 1, 1, 1, 1], dtype=uint8)\\nI would like a method that worked for whatever m I have in the code. Given an n-element integer array, I want to process it as above, then compute exclusive OR of all the rows to generate a (1, m) matrix.\\nA:\\n<code>\\nimport numpy as np\\na = np.array([1, 2, 3, 4, 5])\\nm = 6\\n</code>\\nresult = ... # put solution in this variable\\nBEGIN SOLUTION\\n<code>\\n\"}","display_format":"code","language":"","answer_status":"published","assets":[],"source_url":"https://ds1000-code-gen.github.io/","history":"initial import","indexing_mode":"index","subproblems":[],"grids":[]}
