how to spllititng array with for loop ?

Here's the code to deal with the second situation where we split the unsorted array into two and sort the first half ascending and the second half descending:

      int[] a = {3, 1, 4, 10, 5, 7, 2, 8, 9, 6}; 
      int temp = 0;

Sorry but I don't see how it's possible to do this using one loop because, until you've sorted it, you don't know what the second half contains.

It should be possible to sort the first half of the (unsorted) array in ascending order and the second half in descending order within a single loop but that's not the same thing. For example if you had this to start with:

int[] a = {3, 1, 4, 10, 5, 7, 2, 8, 9, 6};

you'd end up with:

1, 3, 4, 5, 10, 9, 8, 7, 6, 2

rather than

1, 2, 3, 4, 5, 10, 9, 8, 7, 6

Perhaps that's what you remembered seeing before?

this is very god , but one thing we can combine this two loops together means both function sorrting and reversing doing it by one loop ? cause as long before i see one programe both function doing it ..... if you can do it , its very good and helpfull for me 

You can't do the second part until you've done the first part. So to combine the two I'd do:

i said i sorrted array but i don't no how is organize with my function look this is my sorrt aray 

It only works if you've sorted the array first and you said you'd done that step already.

thanks for your quieck answer but it doesn't work with my function 


this is all of the function but i don't no why it didn't do it !!! 

Once you've sorted the array, you can reverse the second half of it using a for loop as follows:
