I am trying to construct a contour plot using matplot in Python with an irregular xy-grid. My x-data is made up of 10 arrays, each having 500 elements. These 500 elements are different for each of the 10 arrays. An simple example might be x = [[0 1 2 3], [0 1 3 5], [0, 2 4 6]]. The y-data is an a...

Challenge at https://www.codewars.com/kata/5629db57620258aa9d000014/train/python Given two strings s1 and s2, we want to visualize how different the two strings are. We will only take into account the lowercase letters (a to z). First let us count the frequency of each lowercase letters in s1 an...

Introduction Suppose we have a dynamic table \$T\$. Let \$\vert T \vert\$ denote the number of elements currently stored in \$T\$, and \$\vert \vert T \vert \vert\$ denote the capacity of \$T\$. Also, suppose we are given two parameters for \$T\$: \$m \in \mathbb{N}\$ is the initial (minimum) cap...
