Simple Arithmetic Formatter

Teacher Wang is teaching simple arithmetic and has collected several problems that students often get wrong. He wants to compile these problems into a practice exercise. To reduce the amount of input work, the arithmetic problem 5+8 should be generated by simply providing the numbers 5 and 8.

Your task is to read two non-negative integers a and b, form an expression in the format \(a+b=c\) (where \(c=a+b\)), and then output the complete expression followed by the total number of characters in that expression. For example, given input 5 8, the first line of the output should be 5+8=13 and the second line should be 6 (since there are 6 characters in "5+8=13").

inputFormat

The input consists of two non-negative integers a and b separated by a space.

outputFormat

The output should contain two lines:

1. The first line displays the arithmetic expression in the format \(a+b=c\) (with no extra spaces), where \(c\) is the sum of \(a\) and \(b\).
2. The second line displays the total number of characters in the expression.
