a number whose only prime factors are 2,3,5, and 7 is call humble number,,write a program to find and display the nth element in this sequence.. sample input : 2,3,4,11,12,13, and 100.. sample output : the 2nd humble number is 2,the 3rd humble number is 3,the 4th humble number is ,the 11th humble number is 12, the 12th humble number is 14, the 13th humble number is 15, the 100th humble number is 450.

a number is perfect if it is equal to the sum of its proper divisor.. 6 is perfect number coz its proper divisors are 1,2 and three.. and 1+2+3=6... a number is deficient if the sum of its proper divisor is less than the number.. sample: 8 is deficient, coz its proper divisors are 1,2 and 4, and 1+2+4=7. abundant number, if the sum of its proper divisor is greater than the number.. sample..12 is abundant coz 1+2+3+4+6=16 which is geater than 12. now write a program that prompts the user for a number, then determines whether the number is perfect,deficient and abundant..
