function solve(input) {
    let result = input.map(Number);
    let currentNum = 0;
    let multi = 1;
    let arr = [];
    let variable = 1;
    let isMulty = false;
    for (let i = 0; i < result.length; i++) {
        if (result[i] <= 9 && result[i] > -1) {

            for (let j = 1; j <= result[i]; j++) {

                variable *= result[j + i];

                isMulty = true;
            }
            if (!isNaN(variable)) {
                arr.push(variable);
            }
            variable=1;
        }
    }
    if (isMulty) {
        let max = Math.max.apply(Math, arr);
        console.log(max);
    }
    else {
        console.log(0);
    }
