From what you have given. the questions means to say, that simply you’ll be given some numbers
for each numbers you can either add number%10 to your answer or multiply it and then finally give the max number
the solution would be, that if number%10 is 0 or 1 then add it or multiply it
corner check, first number has to be only added since u start with 0, if the first number’s % with 10 is 1 then add the second number as well besides that you will only multiply
