Increase the number of iterations to 12.

If you need to increase the number of iterations to 12 in a Go loop, it is enough to change the loop condition. For example, if you have a loop:

for i := 0; i < 10; i++ {
    // loop body
}

then you should replace 10 with 12:

for i := 0; i < 12; i++ {
    // loop body
}

Thus, the loop will execute 12 times.
