Problema
Walk through the list once and track both the smallest and the largest value.
Implement min_and_max(numbers).
Input
numbers: A non-empty list of integers.
Output
Return [smallest, largest].
Vincoli
1 ≤ length ≤ 100,000
Esempi
Esempio 1
Input:
numbers = [4, -2, 9, 0]
Output atteso:
expected = [-2, 9]Input:
std::vector<long long> numbers = {4, -2, 9, 0};
Output atteso:
std::vector<long long> expected = {-2, 9};Input:
long[] numbers = new long[] {4, -2, 9, 0};
Output atteso:
long[] expected = new long[] {-2, 9};Spiegazione
The smallest value is -2 and the largest is 9: [-2, 9].
Esempio 2
Input:
numbers = [7]
Output atteso:
expected = [7, 7]Input:
std::vector<long long> numbers = {7};
Output atteso:
std::vector<long long> expected = {7, 7};Input:
long[] numbers = new long[] {7};
Output atteso:
long[] expected = new long[] {7, 7};Spiegazione
With one value it is both the smallest and largest: [7, 7].
