|
+// - if there were no breaks, at the end of the inner loop, it's set to 0, which

+// causes it to exit (the inner loop is run exactly once)
|
|
+// - at the end of the outer loop, it's inverted, so it becomes 1 again, allowing
|
|
+// the outer loop to continue executing
|
|
+// - if there was a break inside the inner loop, it will exit with control still
