Complete the following method linearSearch which should return the location of findVal in the array list. If findVal does not exist, linearSearch will return -1.
int linearSearch( double[] list, double findVal ) {
//Code goes here.
}

2. Complete the following method numOccurences which should return the # of occurrences of findVal in list. If findVal = 7 and 7 occurs 10 times in the array list, then the method should return 10.

Complete the following method binarySearch.   Fill in each blank below.
int binarySearch(int [] stuff, int val )
{
    int bot= 0, top = stuff.length-1;
    while(bot<=top)
    {
        int middle =  __________________________
        if (stuff[middle] == val)  return middle;
        else
            if (stuff[middle] > val)
                 top = _____________________
            else
                 bot = _____________________
}
return -1;
}
 Write the  binarySearch using recursion.  

public static int binarySearch(int[] stuff, int item, int bot, int top)
{
    //Code goes here.
}
