An interview question with amazon

normalizeUnix()

var str = '/var/www/./../html/.././webkit';
var str2 = './var/www/./html/testdir/../assets/.';

function normalizeUnix(string) { 
	var arr = string.split('/'); 
  if(arr[0] == '')
  	arr.splice(0, 1);
    
  for(var i = 0; i < arr.length; i++) {  
    if(arr[i] == '.') { 
			arr.splice(i, 1);   
      i--;
    }else if(arr[i] == '..') { 
      i--;
			arr.splice(i, 2); 
      i--; 
    } 
  }
  return arr;
}

console.log(normalizeUnix(str));
console.log(normalizeUnix(str2));

I was asked this question during a phone interview with amazon for a web development position.

I let my nerves get the best of me..
