((nums.reshape(-1,1) & (2**np.arange(8))) != 0).astype(int): Converts the boolean array obtained in the previous step into an integer array, where True becomes 1 and False becomes 0. This array represents the binary representation of the numbers in nums, but the order of the bi...
# Convert the array into binary using NumPy binary_repr function binary_array = np.array([np.binary_repr(num) for num in int_array]) In this step, we use thenp.binary_repr()function to convert the integers in the int_array into their binary equivalents. We do this by iterating ov...
