#### Example Programs

**Program [1]**

A Composite Magic number is a positive integer which is composite as well as a magic number. Composite number: A composite number is a number that has more than two factors.

For example: 10

Factors are: 1, 2, 5, 10

Magic number: A magic number is a number in which the eventual sum of the digits is equal to 1

For example: 28=2+8=10=1+0=1

Accept two positive integers m and n, where m is less than n as user input. Display the number of Composite magic integers that are in the range between m and n (both inclusive) and output them along with the frequency, in the format specified below.

Test your program with the sample data and some random data:

**Example 1:**

INPUT: m = 10 n = 100

OUTPUT:

THE COMPOSITE MAGIC INTEGERS ARE: 10, 28, 46, 55, 64, 82, 91, 100

FREQUENCY OF COMPOSITE MAGIC INTEGERS IS: 8

**Example 2:**

INPUT: m = 1200 n = 1300

OUTPUT:

THE COMPOSITE MAGIC INTEGERS ARE:

1207, 1216, 1225, 1234, 1243, 1252, 1261, 1270, 1288

FREQUENCY OF COMPOSITE MAGIC INTEGERS IS: 9

**Example 3:**

INPUT: m = 120 n = 99

OUTPUT:

INVALID INPUT
