Please help me with this short coding assignment.

Coding Challenge: At the end of Mechatronics training, we were able to turn on an LED with a button (long-arm switch). The coding challenge is to reduce the lines of code needed to do the same operation. Specifically, reduce the lines of code inside the void loop function, as seen below, down to one line (one semicolon). void loop() { button1 = robot.readButton (1); if (button1 0) { robot. LED (1,1); } else{ robot. LED (1,0); } }
