AGE DESTRIBUTION(codeeval)

久しぶりにCodeEval のぞいたら、問題が増えていたのでやってみました。

CHALLENGE DESCRIPTION:

In this challenge, we are analyzing the ages of people to determine their status.
If the age is from 0 to 2 the child should be with parents at home, print : 'Home' 
If the age is from 3 to 4 the child should visit preschool, print : 'Preschool' 
If the age is from 5 to 11 the child should visit elementary school, print : 'Elementary school' 
From 12 to 14: 'Middle school' 
From 15 to 18: 'High school' 
From 19 to 22: 'College'
From 23 to 65: 'Work'
From 66 to 100: 'Retirement'
If the age of the person less than 0 or more than 100 - it might be an alien - print: "This program is for humans"
