Overview

Mathpipe is a program that performs various simple operations on input numbers. It reads a jagged array from standard input and applies requested operations on each row, printing the result to standard output. Errors are reported to stderr.

• COUNT: Prints the number of elements in a given array.
• MIN: Prints the minimum value in a given array.
• MAX: Prints the maximum value in a given array.
• SUM: Prints the sum of values in a given array.
• AVG: Prints the average value of elements in a given array.
• PAVG: Prints the pseudo-average (avg of min and max) of elements in a given array.
• PRINT: Prints the numbers in the array.
• FILTER: Prints numbers passing a filter criteria.
• SHIFT: Adds a value to each element of the array.
