Problem explanation

#1

HI,
Is it possible that neither we are reaching infinity nor we are getting cycle?

#2

hello @vatsal50

no its not possible.

see we are given int
and int can have atmost 9 - 10 digits(let say 10) , so after one step the highest number that we can get is 810 ( all 10 digits are 9 , 10 * 9 ^ 2 )

so here we can say our range is bounded [0…810]
hence it will take finite steps . . . .

#3

Please explain this int can have atmost 9 - 10 digits(let say 10)

#4

largest number that an int datatype can hold wiLL have atmost 10 digits.

#5

just check how many digit INT_MAX constant has.
