How to count the maximum consecutive set of numbers in an array with TypeScript

Answer 1

function countMaxConsecutiveSetOfNumbers(arr : number[]) {
    const size : number = arr.length;
    let set = new Set();
    
    for (let i = 0; i < size; i++) {
        set.add(arr[i]);
    }
    
    let mx : number = 0;
    for (let i : number = 0; i < size; i++) {
        if (set.has(arr[i])) {
            let temp : number = arr[i];
            while (set.has(temp)) {
                temp++;
            }
            mx = Math.max(mx,temp - arr[i]);
        }
    }
    return mx;
}

const arr : number[] = [22, 3, 21, 32, 24, 31, 4, 99, 23];

// 21 22 23 24

console.log(countMaxConsecutiveSetOfNumbers(arr));
