Getting Top 10 Highest Numbers From Array?

Question

I am having a bit of a issue. I have an NSMutableDictionary with 10 NSMutableArrays in it. Each array has somewhere between 0-10 numbers which could each be any integer, e.g. 12

You have to short your array in descending order using 'C' logic. Here i'm going to give an example according to your condition....

// adding 20 elements in an array, suppose this is your original array (array1).
NSMutableArray *array1 = [[NSMutableArray alloc]init];

for(int i=0;i<20;i++)
{
    NSString *str = [NSString stringWithFormat:@"%d",(i*4)];
    [array1 addObject:str];
}

//make a copy of your original array 
NSMutableArray *array2 = [[NSMutableArray alloc]initWithArray:array1];


// this is the array which will get your sorting list
NSMutableArray *array3 = [[NSMutableArray alloc]init];

//declare an integer for compare as a maximum number and it to 0 initially
int max = 0;


// this is the logic to sort an array
for(int i=0;i<20;i++)
{
    for(int j=0;j<[array2 count];j++)
    {
        int f = [[array2 objectAtIndex:j] intValue];
        if(max
