Mоже ли някой да ми помогне с задачата от миналият mid exam 02.Array Modifier,решавам я изкарва ми вярно примерните входове но джъдж ми казва 70/100.https://pastebin.com/qbU5CB9P

ето и задачата ->https://judge.softuni.org/Contests/Practice/Index/2474#1

function arrayCommands(array){
    let index = 0
    let numbers = String(array[0]).split(' ')
    let arrayOfCommands = []
    let command = ''
    let sumForMultiplier = 0
    let decreasedArray = []
 
    index++
  while(command != 'end'){
    command = array[index].split(' ')
    arrayOfCommands.push(array[index])
    let firstCommand = command[0]
 
      if(firstCommand === 'swap'){
        let temp = numbers[command[1]]
        numbers[command[1]] = numbers[command[2]]
        numbers[command[2]] = temp
 
      }else if(firstCommand === 'multiply'){
        sumForMultiplier = Number(numbers[command[1]]) * Number(numbers[command[2]])
        numbers[command[1]] = sumForMultiplier
 
      }else if(firstCommand === 'decrease'){
        for(let i = 0;i < numbers.length;i++){
          decreasedArray.push(numbers[i] - 1)
 
        }
      }
 
    index++
 
  }
  if(decresedArray === undefined || decresaedArray.length == 0) {
    console.log(numbers.join(', '))
  }else{
    console.log(decreasedArray.join(', '));
  }
 
}
