The Min Max algorithm efficiently finds the minimum (min) and maximum (max) values in an array of numbers. This approach involves traversing the array while keeping track of the current minimum and maximum values encountered.
Problem Description
Given an array A, find the size of the smallest subarray such that it contains at least one occurrence of the maximum value of the array and at least one occurrence of the minimum value of the array.
Problem Constraints
1 <= |A| <= 2000
Input Format
First and only argument is vector A
Output Format
Return the length of the smallest subarray which has at least one occurrence of minimum and maximum element of the array.
Example Input / Output
Input 1:
A = [1, 3, 2]
Input 2:
A = [2, 6, 1, 6, 9]
Output 1:
2
Output 2:
3
Example Explanation
Explanation 1:
Take the 1st and 2nd elements as they are the minimum and maximum elements respectively.
Explanation 2:
Take the last 3 elements of the array.
JavaScript Output
function findMinMax(arr) {
if (arr.length === 0) {
return { min: null, max: null };
}
let min = arr[0];
let max = arr[0];
for (let i = 1; i < arr.length; i++) {
if (arr[i] < min) {
min = arr[i];
}
if (arr[i] > max) {
max = arr[i];
}
}
return { min: min, max: max };
}
// Example usage:
const array = [3, 5, 1, 8, 2, 9, -1];
const result = findMinMax(array);
console.log(`Min: ${result.min}, Max: ${result.max}`); // Output: Min: -1, Max: 9
