Complete the given function growth that will calculate how many years until a town reaches a given population.  The population will begin at a given start population.  At the end of each year, the population will grow by a given percent, and then the population will change by a constant value called aug (inhabitants coming or leaving each year).  Calculate how many years until it reaches the given goal population.
 
Note: Population should always be an integer, so always remove any decimal portion after each year.  (Always round down)
 
Input Format:
The function will have 4 arguments
start - the initial population
percent - the percentage of population growth each year.  (ex:  2  represents 2% growth)
aug - the constant number of inhabitants coming or leaving each year
goal - the population to meet or exceed

Mutations
Return true if the string in the first element of the array contains all of the letters of the string in the second element of the array.

For example, ["hello", "Hello"], should return true because all of the letters in the second string are present in the first, ignoring case.

The arguments ["hello", "hey"] should return false because the string "hello" does not contain a "y".

Lastly, ["Alien", "line"], should return true because all of the letters in "line" are present in "Alien".

Truncate a string
Truncate a string (first argument) if it is longer than the given maximum string length (second argument). Return the truncated string with a ... ending.

Note that inserting the three dots to the end will add to the string length.

However, if the given maximum string length num is less than or equal to 3, then the addition of the three dots does not add to the string length in determining the truncated string.

Return Largest Numbers in Arrays
Return an array consisting of the largest number from each provided sub-array. For simplicity, the provided array will contain exactly 4 sub-arrays.

Remember, you can iterate through an array with a simple for loop, and access each member with array syntax arr[i].

function largestOfFour(arr) {
 for(var i=0 ; i < arr.length; i++) {
  	arr[i].sort(function(a,b) {
