//Game of 3s
//If the number is divisible by 3, divide it by 3.
//If it's not, either add 1 or subtract 1 (to make it divisible by 3), then divide it by 3.

// define a function with parameter as number
// make a while loop start with num and end at 1
//condition to check if the number i is devisible by 3 
//true , divide by number of 3
// false, ass -1 or +1 to make it divide by 3 
// return the number 1
