👉 Surmisable is a concept in mathematics and computer science, which refers to an algorithm or procedure that can be implemented by a machine under any circumstances. It's often used in scenarios where an algorithm needs to be adaptable to different inputs without having to change it entirely. For example, consider the following algorithm: ``` function calculateSum(n: number): number { let sum = 0; for (let i = 1; i <= n; i++) { sum += i
