OCaml Code: The goal of this project is to understand and build an interpreter for a small, OCaml-like, stackbased bytecode language. Make sure that the code compiles correctly and provide the code with the screenshot of the output. Make sure to have the following methods below: -Push integers, strings, and names on the stack -Push booleans -Pushing an error literal or unit literal will push :error: or :unit:onto the stack, respectively -Command pop removes the top value from the stack -The command add refers to integer addition. Since this is a binary operator, it consumes the toptwo values in the stack, calculates the sum and pushes the result back to the stack - Command sub refers to integer subtraction -Command mul refers to integer multiplication -Command div refers to integer division -Command rem refers to the remainder of integer division -Command neg is to calculate the negation of an integer -Command swap interchanges the top two elements in the stack, meaning that the…
