Solution 1

We need to output all integers from 1 to 100, inclusive. In a high-level programming language, we would typically use a loop as follows.

int = 1;                 // Start at 1.
loop:                    // Start of "loop".
    output = int;        // Print the integer.
    int++;               // Increment the current integer.
    check int < 101;     // Is integer < 101?
    jump if true: loop;  // If so, go to "loop".
    jump if false: end;  // Otherwise, go to "end".
end:                     // End of program.

Solution 2

Similar to Solution 1. We can shave off a few lines by noticing that, from the previous solution, the last two lines are not necessary. If the loop conditional is false, then we automatically exit the loop and reach the end of the program. Also note that we do not need a loop conditional. Use a loop to print as many integers as necessary. Once the game detects we have output the required number of integers, the program ends.

int = 1;            // Start at 1.
loop:               // Start of "loop".
    output = int;   // Print the integer.
    int++;          // Increment the integer.
    jump to: loop;  // Go to "loop".

Solution 3

Suppose we want to use 2 lines to output all integers from 1 to 100, inclusive. The register int is initially zero. Incrementing that register would give us 1 and we can output that value. Continue incrementing and outputting until we have output all required integers. This solution is optimal, according to the game.

int++;         // Increment the integer.
output = int;  // Print the integer.
