Haskell and Ruby

This site also takes programs written in Haskell 2010 and Ruby 3.2. These languages were added by enthusiasts in the past so we don't actively support them. If they work for you then you may still use them.

I/O and Documentation

• Get input from standard input and print to standard output.
• You may use the standard online documentation for your language during and NZIC contest.

Example

Write a program to add two numbers and print the result. Numbers will be space separated on a single line (see the sample input and output below).

Submit

• Go to the submit tab and upload your code. Select your chosen language from the dropdown.
• Do not use input prompts (e.g. Input a number:) because these will be evaluated as incorrect output. See the walk-through below to understand why.
• Walk-through example and explanation. This example uses Python but applies to all languages when used on this site.
• Understanding submission feedback.

Sample Explanation

3 + 4 = 7
