//
// Zig 'while' statements can have an optional 'continue expression'
// which runs every time the while loop continues (either at the
// end of the loop or when an explicit 'continue' is invoked (we'll
// try those out next):
//
//     while (condition) : (continue expression)
//         ...
//     }
//
// Example:
//
//     var foo = 2;
//     while (foo<10) : (foo+=2)
//         // Do something with even numbers less than 10...
//     }
//
// See if you can re-write the last exercise using a continue
// expression:
//
const std = @import("std");
