function Main(input) {
  if (input == 'SUN') {
    console.log(7)
  }
  if (input == 'MON') {
    console.log(6)
  }
  if (input == 'TUE') {
    console.log(5)
  }
  if (input == 'WED') {
    console.log(4)
  }
  if (input == 'THU') {
    console.log(3)
  }
  if (input == 'FRI') {
    console.log(2)
  }
  if (input == 'SAT') {
    console.log(1)
  }
  // switch (input) {
  //   case 'SUN':
  //     console.log(parseInt(7).toString())
  //     break
  //   case 'MON':
  //     console.log(parseInt(6).toString())
  //     break
  //   case 'TUE':
  //     console.log(parseInt(5).toString())
  //     break
  //   case 'WED':
  //     console.log(parseInt(4).toString())
  //     break
  //   case 'THU':
  //     console.log(parseInt(3).toString())
  //     break
  //   case 'FRI':
  //     console.log(parseInt(2).toString())
  //     break
  //   default:
  //     console.log(parseInt(1).toString())
