Suppose there are three variables X, Y and Z with these types: X: integer that is divisible by 2 Y: integer that is divisible by 4 Z: integer For each of the following assignments, knowing nothing about the values of the variables except their types, answer whether a language system can tell before running the program whether the assignment is safe? Why or why not? a. X: Y b. X: = Z C. Y: Y + 1

ARDUINO LANGUAGE We have two push buttons and three LEDs (Red, Green and Blue). When the user presses button 1, the red LED will turn on and the blue LED will turnoff. If the user presses button 1 again the red LED will turn off and the blue LED willturn on. When the user presses button 2, the green LED will blink on and off 3 times. Considera delay of 1 second between blinks.Note: while the green LED is blinking, button 1 may not respond to presses. This is normaland acceptable for your code.
