HELP WITH THE TODOs'

/ This application uses button 1, LED 1, and LED 2 on Launchpad // Pushing button 1 toggles LED1 status. // Pushing a button consists of "pressing, followed by releasing". // This a typical push-button behavior: as soon as you press the button, LED toggles, // as you keep the button pressed nothing happens, once you release it, if you press again, the LED toggles again.
