Highest and Lowest

In this little assignment you are given a string of space separated numbers, and have to return the highest and lowest number.

Example:

highAndLow("1 2 3 4 5");  // return "5 1"
highAndLow("1 2 -3 4 5"); // return "5 -3"
highAndLow("1 9 3 4 -5"); // return "9 -5"

Kata.HighAndLow("1 2 3 4 5");  // return "5 1"
Kata.HighAndLow("1 2 -3 4 5"); // return "5 -3"
Kata.HighAndLow("1 9 3 4 -5"); // return "9 -5"

highAndLow "1 2 3 4 5"  // return "5 1"
highAndLow "1 2 -3 4 5" // return "5 -3"
highAndLow "1 9 3 4 -5" // return "9 -5"

highAndLow("1 2 3 4 5");  // return "5 1"
highAndLow("1 2 -3 4 5"); // return "5 -3"
highAndLow("1 9 3 4 -5"); // return "9 -5"

highAndLow("1 2 3 4 5");  // return "5 1"
highAndLow("1 2 -3 4 5"); // return "5 -3"
highAndLow("1 9 3 4 -5"); // return "9 -5"

highAndLow("1 2 3 4 5");  // return "5 1"
highAndLow("1 2 -3 4 5"); // return "5 -3"
highAndLow("1 9 3 4 -5"); // return "9 -5"

highAndLow("1 2 3 4 5")  # return "5 1"
highAndLow("1 2 -3 4 5") # return "5 -3"
highAndLow("1 9 3 4 -5") # return "9 -5"

high_and_low("1 2 3 4 5")  # return "5 1"
high_and_low("1 2 -3 4 5") # return "5 -3"
high_and_low("1 9 3 4 -5") # return "9 -5"

high_and_low("1 2 3 4 5")  # return "5 1"
high_and_low("1 2 -3 4 5") # return "5 -3"
high_and_low("1 9 3 4 -5") # return "9 -5"

high_and_low("1 2 3 4 5")  # return "5 1"
high_and_low("1 2 -3 4 5") # return "5 -3"
high_and_low("1 9 3 4 -5") # return "9 -5"

high_and_low("1 2 3 4 5")  # return "5 1"
high_and_low("1 2 -3 4 5") # return "5 -3"
high_and_low("1 9 3 4 -5") # return "9 -5"

highAndLow("1 2 3 4 5")  // return "5 1"
highAndLow("1 2 -3 4 5") // return "5 -3"
highAndLow("1 9 3 4 -5") // return "9 -5"

highAndLow "1 2 3 4 5")  # return "5 1"
highAndLow "1 2 -3 4 5") # return "5 -3"
highAndLow "1 9 3 4 -5") # return "9 -5"

HighAndLow("1 2 3 4 5")  // return "5 1"
HighAndLow("1 2 -3 4 5") // return "5 -3"
HighAndLow("1 9 3 4 -5") // return "9 -5"

highAndLow("1 2 3 4 5")  // return "5 1"
highAndLow("1 2 -3 4 5") // return "5 -3"
highAndLow("1 9 3 4 -5") // return "9 -5"

Kata.high_and_low("1 2 3 4 5")  # return "5 1"
Kata.high_and_low("1 2 -3 4 5") # return "5 -3"
Kata.high_and_low("1 9 3 4 -5") # return "9 -5"

Notes:

  • All numbers are valid Int32, no need to validate them.
  • There will always be at least one number in the input string.
  • Output string must be two numbers separated by a single space, and highest number is first.

Solution

function highAndLow($numbers) {
  $numbers_arr = explode(" ", $numbers);
  return max($numbers_arr) . " " . min($numbers_arr);
}
