Free-Form Input

You are to read a sequence of lines and, for each line, compute the sum of the numbers on that line. Each line contains one or more numbers. Numbers are separated by commas. A number may be positive or negative (preceded by a minus sign), and may or may not contain a decimal part. Blanks may be imbedded between numbers and within numbers.

Input

Each line of input contains up to $72$ characters and adheres to the format described above. Every number will be at most $10^6$ in absolute value and contain at most $6$ digits after the decimal point.

For each line of input, print a single number that is the sum of all numbers on that line. Your answer will be accepted if it is within an absolute or relative error of $1e-6$ of the correct solution.
