• Input day number from user, Store it in variable 'day'
• Switch the value of 'day', use switch(day).
• There can be 7 possible attempt of day, from 1 to 7. Therefore write 7 case inside switch. In addition, add default case as an else block.
• For case 1: print "MONDAY", 
• For case 2: print "TUESDAY" and so on. 
• Print "SUNDAY" for case 7.
• If any case does not matches then, for default: case print "Invalid Input".
