quick java question

private static char[] quicksort (char[] array , int left , int right) {
if (left < right) {
int p = partition(array , left, right);
quicksort(array, left, p - 1 );
quicksort(array, p + 1 , right);
}
for (char i : array)
System.out.print(i + ” ”);
System.out.println();
return array;
}
private static int partition(char[] a, int left, int right) {
char p = a[left];
int l = left + 1, r = right;
while (l < r) {
while (l < right && a[l] < p) l++;
while (r > left && a[r] >= p) r--;
if (l < r) {
char temp = a[l];
a[l] = a[r];
a[r] = temp;
}
}
a[left] = a[r];
a[r] = p;
return r;
}

hi guys just a quick question regarding the above coding, i know that the above coding returns the following
B I G C O M P U T E R
B C E G I M P U T O R
B C E G I M P U T O R
B C E G I M P U T O R
B C E G I M P U T O R
B C E G I M O P T U R
B C E G I M O P R T U
B C E G I M O P R T U
B C E G I M O P R T U
B C E G I M O P R T U
B C E G I M O P R T U
B C E G I M O P R T U
B C E G I M O P R T U
when the sequence BIGCOMPUTER is used but my question is can someone explain to me what is happening in the code and how?
i know abit about the quick-sort algorithm but it doesnt seem to be the same in the above example.
