+/**
+ * @file magic_number.cpp
+ * @brief A simple program to check if the given number is a magic number or not.
+ * A number is said to be a magic number, if the sum of its digits are calculated 
+ * till a single digit recursively by adding the sum of the digits after every addition. 
+ * If the single digit comes out to be 1,then the number is a magic number.
+ * @detail This is a shortcut method to verify Magic Number. 
+ * On dividing the input by 9, if the remainder is 1 then the number is a magic number else not. 
+ * The divisibility rule of 9 says that a number is divisible by 9 if the sum of its digits 
+ * are also divisible by 9. Therefore, if a number is divisible by 9, then, recursively, 
+ * all the digit sums are also divisible by 9. The final digit sum is always 9. 
+ * An increase of 1 in the original number will increase the ultimate value by 1, 
+ * making it 10 and the ultimate sum will be 1, thus verifying that it is a magic number.
