LeetCode 167: Two Sum II - Input array is sorted

function twoSum(numbers: number[], target: number): number[] {
    let i = 0;
    let j = numbers.length - 1;

    const answers: number[] = [];

    while (i < j) {
        const sum = numbers[i] + numbers[j];

        if (sum === target) {
            answers.push(++i, ++j);
            break;
        }
        else if (sum > target) j--;
        else i++;
    }

    return answers;
