Input/Output for pairs of numbers: Difference between revisions

'''Works with gojq, the Go implementation of jq'''

The solution below assumes the input is in a file named input.txt, and is quite lenient about the presentation of the numbers. For example, it does not require that each pair of numbers be presented on the same line.

<lang sh>

< input.txt jq -n '

input as $n

| if ($n | type != "number") or ($n < 1)

then "Number of pairs must be a positive integer." | error

else range(0; $n)

| [input,input] | add

end'

</lang>
