проблем с 02. Treasure Hunt от 06. Programming Fundamentals Mid Exam Retake

Здравейте, получавам 10/100 и не знам как да оправя грешките, някой може ли да ми помогне ?

Благодаря :)

задача: https://judge.softuni.org/Contests/Practice/Index/1773#1

код:

function solve(input){
let state = input.shift().split("|")
let actions = {
"Loot": loot, "Drop": drop, "Steal": steal
}
function loot(items){
items.forEach(x => {
if(!state.includes(x)) state.unshift(x)
})
}
function drop(index){
let item = state[index]
if(state[index] !== undefined)
state.splice(item, 1)
state.push(item)
}
function steal(count){
let items = state.splice(-count)
console.log(items.join(", "))
}
input.forEach(x => {
if(x !== "Yohoho!"){
const [a, b] = x.split(" ").map(x => (isNaN(x) ? x : Number(x)))
try{
actions[a](b)
}catch(e){

}
}
})
let avg = state.reduce((a, v) => a + v.length, 0) / state.length

state.length === 0 ? console.log("Failed treasure hunt.")
: console.log(`Average treasure gain: ${avg.toFixed(2)} pirate credits.`)
}

Demo code, ;-) =>

function treasureHunt(arr) {
    let initialLoot = arr.shift().split("|");
    
    for (const line of arr) {
        let [command, ...currentCommandArray] = line.split(" ");

        switch (command) {
            case "Loot":
                for (let el of currentCommandArray) {
                    if (!initialLoot.includes(el)) {
                        initialLoot.unshift(el);
                    }
                }

                break;
            case "Drop":
                let startingIndex = Number(currentCommandArray[0]);

                if (startingIndex >= 0 && startingIndex < initialLoot.length) {
                    let oldLoot = initialLoot.splice(startingIndex, 1)
                    initialLoot.push(...oldLoot);
                }

                break;
            case "Steal":
                let index = Number(currentCommandArray);
                let stolenTreasure = initialLoot.slice(-index);
                initialLoot.splice(-index);
                console.log(stolenTreasure.join(', '));

                break;
        }
    }

    let itemSum = initialLoot.reduce((sum, initialTresure) => {
        return sum + initialTresure.length;
    }, 0) / initialLoot.length;

    if (initialLoot.length > 0) {
        console.log(`Average treasure gain: ${itemSum.toFixed(2)} pirate credits.`);
    } else {
        console.log(`Failed treasure hunt.`);
    }
}

You've got the solution in front of you, no one will help you during the exams and the exams will get more and more difficult with each further level (dito when you land a job at a software company - no senior will be around to help you out) !!!
