You are tasked with implementing a feature to evaluate string expressions that utilize lambda notation in programming. The strings will represent lambda expressions that define a function by specifying its parameters and body. Your goal is to write a function that takes two arguments: 1. A string that represents a lambda expression in the form of `λx.E`, indicating a function that takes the parameter `x` and evaluates the expression `E`. 2. The second argument is a value that you will provide for the parameter `x`. The function should then evaluate the expression using the provided value and return the result. To simplify the evaluation process, assume that `E` consists only of basic arithmetic operations and constants. For example, given the input `λx.x + 1` and the value `2`, your function should return `3` as it substitutes `2` for `x` in the expression. Design your implementation to handle multiple expressions and types of computations while ensuring correct evaluation based on arithmetic rules.

I’ve been diving into some interesting concepts lately involving lambda expressions and how they can be evaluated programmatically. I came across this fun challenge that I think could spark your curiosity! Imagine you’re working on a feature that evaluates string representations ...Read more
