//Question 1
/*
var items,costs,item,cost,totalCost,percent;
//Initializing Variables
items = [];
costs = [];
totalCost=0;

do{//Add items to array
  item = prompt("Enter an item. Enter STOP to stop.").toUpperCase();
  if (item != "STOP"){
  cost = parseFloat(prompt("Enter the price for "+item));
      items.push(item);
      costs.push(cost);
      totalCost+=cost;
  }
}while(item != "STOP");

//Start table
document.write('<table border="1"><tr><th>Item</th><th>Percentage</th></tr>');

for(i=0;i<items.length;i++){//Iterate array and print to table
  percent=(costs[i]/totalCost)*100;
  percent=percent.toFixed(2);
  document.write("<tr><td>",items[i],"</td><td>",percent,"%</td></tr>");
}

document.write("</table>");

//Question 2
//The first block of code is using JS Split, while the other is a custom-made split.

/*
var word,wordArr,ind;
//Initializing variables
word = prompt("Enter a word");
for (i=0;i<word.length;i++){//Remove commas
  if (word.charAt(i) == ","){
    word = word.slice(0,i) + word.slice(i+1);
  }
}
wordArr = word.split(" ");
document.write(wordArr);
*/

/*
//Homemade Split!
var word,wordArr,wordLittle;
//Initialize variables
word = prompt("Enter a word");
wordArr = [];
wordLittle = "";
//Start iterating array
for(i=0;i<word.length;i++){
    if (word.charAt(i) == " "){//Check if there is a space
      wordArr.push(wordLittle);
      wordLittle = "";
    }
    else if (word.charAt(i) == ","){//Check if there is a comma
      
    }
    else{
      wordLittle=wordLittle+word.charAt(i);//Add character to temp word
    }
  if(i==word.length-1){//If at end, push the rest to array
    wordArr.push(wordLittle);
  }
 }
document.write(wordArr);
