Write a function named alarm$\_$clock. The function has two parameters. The first parameter is an

integer named day and encodes the day of the week: $0=$Sun, $1=$Mon, $2=$Tue, $...,6=$Sat. The second

parameter is a boolean named vacation, and it is true when we are on vacation. The function returns

an integer that indicates when the alarm will ring. On weekdays $($non$-$vacations$),$ the alarm should ring

at $7$ a$.$m$.,$ i$.$e$.,$ the function should return $7.$ On weekends $($non$-$vacations$)$ and vacations $($weekdays$),$ the

alarm should ring at $10$ a$.$m$,$ i$.$e$.,$ the function should return $10.$ On vacation $($weekend$),$ the alarm should

be off, i$.$e$.,$ the function should return $-1.$
