Daily Challenge #40 - Counting Sheep

You're having trouble falling asleep, so your challenge today is to count sheep!

Given a non-negative integer, 3 for example, return a string with a murmur: "1 sheep...2 sheep...3 sheep...". Input will always be valid, i.e. no negative integers.

Happy Coding!

This was quite a simple one so I decided to spice it up with emoji! Also, next-gen sleep simulation at the end.

Code:

# -*- coding: UTF-8 -*-

def countSheep(sheepToCount):
        sheepString = ""
        outputString = ""
        for i in range(sheepToCount):
                sheepString += "🐑 "
                outputString += "{}... ".format(sheepString)
        outputString +="ZZZzzzzzzz"
        print(outputString)

countSheep(5)

Output:

🐑 ... 🐑 🐑 ... 🐑 🐑 🐑 ... 🐑 🐑 🐑 🐑 ... 🐑 🐑 🐑 🐑 🐑 ... ZZZzzzzzzz

Did anybody talk about oneliner?

f=(i)=>[...Array(i)].map((_,i)=>`${i+1} sheep... `).join``

And the results

f(10);
// "1 sheep... 2 sheep... 3 sheep... 4 sheep... 5 sheep... 6 sheep... 7 sheep... 8 sheep... 9 sheep... 10 sheep... "

[Andy Mardell]

This is sweet. Something similar but with more Array and less map:

const f = i => Array.from(Array(i), (_, i) => `${i + 1} sheep... `).join``

or

const f = i => Array.from({ length: i }, (_, i) => `${i + 1} sheep... `).join``

Scheme

(define (countSheep n)
  (if (< n 1) 
    ""
    (string-append (countSheep (- n 1)) (number->string n) " sheep...")
  )
)

A demo can be seen in Repl.it. The function would be called (countSheep 4) and the result would be:

"1 sheep...2 sheep...3 sheep...4 sheep..."

PHP

<?php

/**
 * Daily Challenge #40 - Counting Sheep
 *
 * @param  int    $number Number of sheeps.
 * @return string
 */
function countingSheep(int $number): string
{
  $text = '';
  for ($i = 1; $i <= $number; $i++) {
    $text .= "$i sheep...";
  }

  return $text;
}


echo countingSheep(3);
// Output: 1 sheep...2 sheep...3 sheep...

PHP

I counted bugs because that is more reflective of what I would do while working :)

I also added a message for if you are able to go to sleep immediately

<?php

function countBugs(int $bugs): string {
  if ($bugs === 0) {
    return "sleep tight..." . PHP_EOL;
  }

  $count = 0;
  $text = ++$count . " bug..." . PHP_EOL;

  while ($count < $bugs) {
    $text .= ++$count . " bugs.." . PHP_EOL;
  }

  return $text;
}

echo "Counting three bugs..." . PHP_EOL;
echo countBugs(3);

echo "Counting no bugs..." . PHP_EOL;
echo countBugs(0);

ruby <3

def count_sheep(n)
  1..n |> map { "#@1 sheep..." } |> join
end

Ruby has pipes now?

[Seiei Miyagi]

Yes! pipeline operator added.

Feature #15799: pipeline operator - Ruby master - Ruby Issue Tracking System

And Numbered parameters.

Feature #4475: default variable name for parameter - Ruby master - Ruby Issue Tracking System

It's not released yet. You can try those new syntax by rbenv install 2.7.0-dev.

[Seiei Miyagi]

Sadly, pipeline operator is reverted.

JavaScript

function cs(n) {
    if (typeof n != "number" && n < 0) return `${n} is not a valid number`;

    let text = "";

    for(let x = 0; x < n; x++) {
        text += `${x} sheep... `
    }

    return text;
}

cs(3) // 0 sheep... 1 sheep... 2 sheep...

[Darryl Norris]

JavaScript

/**
 * Daily Challenge #40 - Counting Sheep
 *
 * @param  {number}        Number of sheeps.
 * @return {string}
 */
const countingSheep = number => {
  // Checking if positive integer or not.
  if (!(number >>> 0 === parseFloat(number))) {
    return `${number} is not a positive integer`;
  }

  let text = '';

  // Building text.
  for (let i = 1; i <= number; i++) {
    text += `${i} sheep...`;
  }
  return text;
};

console.log(countingSheep(3));
// Output: 1 sheep...2 sheep...3 sheep...

My solution in js

const murmur = (times) => Array(times).fill()
                                      .map((value, index) => `${index+1} sheep...`)
                                      .join(' ');

[peter279k]

Here is the simple solution with PHP:

function countsheep($num){
  $sheepString = "";

  for ($index=1; $index<=$num; $index++) {
    $sheepString .= (string)$index . " sheep...";
  }

  return $sheepString;
}
