Question 1

Write a program which reads a string as an input then it counts number of occurrences for each letter, and then displays the letters which occurred 3 times or more. Note that your string may contain ASCII characters other than letters, but we want to count letters only. Also note that small and capital letters are equivalent (no difference between uppercase and lowercase letters).

Sample input/output (inputs are underlined):?Enter a string: Smile! You are a CS student. Aren't you?

Letters which occurred 3 times or more are: a, e, s, t, u

Question 2

A sequence of n > 0 integers is called a jolly jumper if the absolute values of the difference between successive elements take on all the values 1 through n-1. For instance, 1 4 2 3 is a jolly jumper, because the absolutes differences are 3, 2, and 1 respectively. The definition implies that any sequence of a single integer is a jolly jumper. You are to write a program to determine whether or not each of a number of sequences is a jolly jumper.

Input

Each line of input contains an integer n <= 3000 followed by n integers representing the sequence.

Output

For each line of input, generate a line of output saying "Jolly" or "Not jolly".

Sample Input

41423?5 1 4 2 -1 6

Sample Output

Jolly

Not jolly

Question 3

Using function template, write one function which sorts an array of any type (int, double, char, string). Then write a program which tests your function on different types.
