Final answer:
The code snippet provided by the student, which uses a 'let' expression in Scheme, can be rewritten using a 'lambda' expression that takes two parameters and immediately applies them to values 2 and 3, creating an equivalent expression that multiplies them together.
Step-by-step explanation:
A student has requested assistance with rewriting a code snippet in Scheme, which involves the use of lambda expressions. The given code ((let ((x 2) (y 3)) (* x y))) is a let expression that defines local variables x and y, then evaluates the expression (* x y) multiplying the two.
Converting to a Lambda Expression
To rewrite the expression using lambda, we need to create an anonymous function that takes two parameters and then apply it immediately to the values 2 and 3. Here's how the rewritten expression using lambda would look:
((lambda (x y) (* x y)) 2 3)
This lambda expression creates an anonymous function with parameters x and y. When the function is called with the arguments 2 and 3, it executes the body (* x y) which multiplies them together, resulting in the same output as the original let expression, which is 6.
