Python: This program will determine if the number entered by the user is happy or not happy. This process involves computing the sum of the squares of the digits of a number. If the number $($n$)$ is not initially $1$ or $42,$ n is updated to be the sum of the squares of its digits. This process is then repeated until n either n reaches $1($happy$)$ or $42($not happy$).$ This process is explained further below. Your program should include the following functions:

sum$\_$of$\_$squares $-$ This function has one parameter of type int and returns the sum of the squares $($an integer$).$ This function can assume the argument is a non$-$negative integer. To calculate the sum of squares, square each digit individually then sum all the squares. For example, sum$\_$of$\_$squares$(123)$ returns $14$ since $1*1+2*2+3*3=14.$ To implement the sum of squares, use the $\%$ and $//$ operators. Remember that for any integer n greater than zero, n $\%10$ will result in the digit in the one's place, and that n $//10$ will result in all the digits except for the digit in the one's place. For example, $123\%10$ is $3$ and $123//10$ is $12.$ An alternative approach is to convert the parameter to a string, then iterate through the characters $($digits$)$ of the string, converting each digits back to a number and squaring it$.$

happy $-$ This function has one parameter of type int and returns a boolean value representing if the parameter number is happy or not happy. For example, happy$(5)$ returns False. To determine if a number is happy or not happy, repeatedly find the sum of the squares until either $1$ or $42$ is reached. If $1$ is reached, the number is happy, and if $42$ is reached, the number is not happy. Each time you call the sum$\_$of$\_$squares function, be sure to print the result to the screen. For example, happy$(13)$ returns True since $1*1+3*3=10,$ and then $1*1+0*0=1,$ and the function call happy$(13)$ would print the following $($also see the sample run above$)$:

$10$

$1$

Note that if $42$ is reached, then the number is stuck in a circle: $42,4*4+2*2=20,2*2+0*0=4,4*4=16,1*1+6*6=37,3*3+7*7=58,5*5+8*8=89,8*8+9*9=145,1*1+4*4+5*5=42($perhaps we should call these numbers dizzy numbers!$).$

main $-$ This function has no parameters and does not return a value. This function is the main driver of the program. It should first print the welcome message. Then it should ask the user to input a number, call the happy function, and based on the returned value, print either:

# is NOT a happy number. :$($

or

# is a happy number. :$)$

where # is the number input by the user.
