Mathematical explanation of Leetcode question: Container With Most Water
I was working on a medium level leetcode question 11. Container With Most Water. Besides the brute force solution with O(n^2), there is an optimal solution with complexity of O(n) by using two pointers from left and right side of the container. I am a little bit confused why this “two pointers” method must include the optimal solution. Does anyone know how to prove the correctness of this algorithm mathematically? This is an algorithm that I don’t know of. Thank you!
All possible combinations in a binary image
I’m trying to create all possible combinations of 0 and 1 in an array that have the shape (n, 10). For example, if we assume an arbitrary combination like this: np.array([0, 0, 1, 1, 0, 0, 1, 1, 0, 0]), how can I generate all possible combinations (which will result in 2^10=1024 arrays)?
Python3 interpret user input string as raw bytes (e.g. x41 == “A”)
