One day, a mathematician defined a new operator ⊙ and used it on his work. However, the mathematician didn't know how to write a program to make a computer calcuate the result. He decided to hire you to write a program for him. The following shows how the new operator ⊙ is defined.
new operator ⊙ : give two integer A,B (A is a three digit integer, B is a two digit integer).
A ⊙ B = (sum of all digits in A) / (sum of all digits in B)
ex: 123 ⊙ 23 = (1+2+3) / (2+3) = 1.20note that : if use visual studio add #pragma warning(disable:4996) in first line to use scanf function
Given two integer A, B (A is three-digit integer, B is two-digit integer)
Print out the result of A ⊙ B (Note that your output should follow three rules)
rule1. the length of the output string is exactly 13 character.
rule2. the result value should be expressed as a floating point number round off to the 2nd decimal place. For example, 3.00 or 6.53
rule3. print '\n' at the end of the output.
