Highest and Lowest

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"

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"

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.

🧠 C++

#include <string>
#include <cstring>
#include <vector>
#include <algorithm>

using namespace std;

string highAndLow(const string& numbers)
{
  char* input = strdup(numbers.c_str());
  vector<int> nums;
  for(char* num = strtok(input, " ");
      num != nullptr; num = strtok(nullptr, " "))
      nums.push_back(atoi(num));

  free(input);
  return to_string(*max_element(nums.begin(), nums.end()))
         + ' ' 
         + to_string(*min_element(nums.begin(), nums.end()));
