Max Sequence of Equal Elements

function maxSequenceOfEqualElements(arr) {
        let currentSequence = [arr[0]];
        let longestSequence = [arr[0]];
        for (let i = 1; i < arr.length; i++) {
            if (arr[i] === currentSequence[0]) {
                currentSequence.push(arr[i]);
            } else {
                if (currentSequence.length > longestSequence.length) {
                    longestSequence = currentSequence;
                }
                currentSequence = [arr[i]];
            }
        }
        if (currentSequence.length > longestSequence.length) {
            longestSequence = currentSequence;
        }
        console.log(longestSequence.join(" "));
}

Още едно решение:

function findLongestSequence(arr) {
    let currentCount = 1;
    let longestCount = 1;
    let currentNum = arr[0];
    let longestNum = arr[0];

    for (let i = 1; i < arr.length; i++) {
        if (arr[i] === currentNum) {
            currentCount++;
        } else {
            if (currentCount > longestCount) {
                longestCount = currentCount;
                longestNum = currentNum;
            }
            currentCount = 1;
            currentNum = arr[i];
        }
    }
    if (currentCount > longestCount) {
        longestCount = currentCount;
        longestNum = currentNum;
    }

    let result = "";
    for (let i = 0; i < longestCount; i++) {
        result += longestNum + " ";
    }
    console.log(result.trim());
}
