The only built in function allowed are len() and range() and it has to be solved with loops or list.

truncatable_prime (n): check whether a number is a "right-truncatable prime" and return bool result. A right-truncatable prime is a prime which remains prime when the last (rightmost) digit is successively removed. (hint: how can you remove the last digit?...) o Assume: n is a positive integer. o Restrictions: no extra restrictions o truncatable_prime (2) truncatable_prime (113) truncatable_prime (5939) True False True #113 and 11 are primes, #5939 ,593, 59,and but I is not 5 are all primes histogram(xs): Given a list of integers named xs, return a string which, when printed, shows a histogram corresponding to the integers. Use lowercase "o" as the display symbol o Assume: xs is a list of non-negative integers; xs could be empty o Restrictions: none currently stated o histogram([3,10,0,5]) o histogram([]) 'ooo!noooooooooo!nInooooolni
