I do not understand why my code is not working, could anyone help me with this one? It is supposed to print a list of palindromes (numbers that are equal to themselves if read backwards) lesser than or equal to the input. When I try to execute it, it writes: /bin/sh: python: command not found.
I have a df with growth variables and often some initial values are 0, in which case it produces infinite values when the value moves from zero to non-zeros.
I have a dataframe that contains 1 years of weekly OHLC data.

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!
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)?
I want to accept user input from the command line using the input() function, and I am expecting that the user provides input like x41x42x43 to input “ABC”. The user MUST enter input in the byte format, they can not provide the alphanumeric equivalent.
I don’t want to use python functions to calculate but I want to implement a function myself. The problem comes when the chain is very long. The program starts to take about 5 minutes.
I can use the following code to generate three dimensional array.
