Mobile coding works. A laptop is faster for long sessions.
Problem
The program reads from standard input an arithmetic expression consisting of non-negative integers, the operators `+`, `-`, `*`, `/`, `%`, round parentheses `(` and `)`, and (optionally) spaces.
Print to standard output two non-negative integers separated by a space:
- the number of **operands** in the expression (each maximal run of consecutive digits is one operand);
- the number of **operators** in the expression (each character among `+`, `-`, `*`, `/`, `%` is one operator).
Parentheses and spaces are **not** counted.
Input format
Input
input.txt
The program reads from standard input a single line containing the expression (at most 1000 characters long). - Length of expression <= 1000. - The expression may or may not be syntactically valid; the program only counts tokens.
Output format
Output
output.txt
The program prints to standard output two non-negative integers separated by a space: the number of operands, then the number of operators.
