Problem Statement

Given a string and defined variables or values, string interpolation is the replacement of defined character sequences in the string by values or variable values.

Note: The task is not to create a string interpolation routine, but to show a language's built-in capability.

Let's start with the solution:

string s1 = "big";
write("Mary had a " + s1 + " lamb");
s1 = "little";
write("Mary also had a ", s1, "lamb");
