    input=input.map(Number);

let budget=input.shift();
    let students=input.shift();
    let flourPrice=input.shift();

   } else {
       console.log(`${(moneyNeeded-budget).toFixed(2)}$ more needed.`)

}

02. Bread Factory

function baker(input){
    let energy=100;
    let coins=100;

let arr=input[0].split("|");

let bonusEnergy=0;

for (let i=0; i<arr.length; i++){

}
    
    console.log("Day completed!");
    console.log(`Coins: ${coins}`);

}

3.Cooking factory

function bakeFactory(input) {
    input = input.slice(0, input.length - 1);
    let batchesObjArr = []

for (let i = 0; i < input.length; i++) {
        let batch = input[i];
        let batchArr = batch.split("#");
        batchArr = batchArr.map(Number);
        let sum = 0;
        batchArr.forEach(element => {
            sum += element;
        });

batchesObjArr.push({
            batch: batchArr,
            totalQ: sum,
            average: sum / batchArr.length
        });

}

batchesObjArr = batchesObjArr.sort(function (a, b) {
        return b.totalQ - a.totalQ;
    })
    let bestBatch = batchesObjArr[0].totalQ;

batchesObjArr = batchesObjArr.filter((element => element.totalQ == bestBatch));
    batchesObjArr = batchesObjArr.sort(function (a, b) {
        return b.average - a.average;
    })

batchesObjArr=batchesObjArr.sort(function(a,b){
        return a.batch.length-b.batch.length;
    })

console.log(`Best Batch quality: ${bestBatch}`);
    console.log(batchesObjArr[0].batch.join(" "));
}
