Yogesh loves numbers. He loves to find weird relations between numbers. One of his favourite things to do is add the digits of random numbers he finds. If the sum of digits is greater than 9 he adds the digits once more. He continues to do this until he obtains a single digit sum. If this sum is equal to 1, he calls it a magic number.
