• Cocoa - array not sorting?

  - by Mike

  I have this set NSMutableSet *mySet = [NSMutableSet setWithObjects: @"2", @"8", @"7", @"0", @"3", nil]; I copy the set to an array and sort it using NSArray *sortedArray = [[mySet allObjects] sortedArrayUsingSelector:@selector(compare:)]; The resulting array is in exactly the same order as the set and is not being sorted. Why? thanks for any help. EDIT: CORRECING A TYPO.

• Iterate Multi-Dimensional Array with Nested Foreach Statement

  - by Tyler Murry

  I think this might be a pretty simple question, but I haven't been able to figure it out yet. If I've got a 2-dimensional array like so: int[,] = new int[2,3] { {1, 2, 3}, {4, 5, 6} }; What's the best way to iterate through each dimension of the array with a nested foreach statement?

• Stack and queue operations on the same array.

  - by Passonate Learner

  Hi. I've been thinking about a program logic, but I cannot draw a conclusion to my problem. Here, I've implemented stack and queue operations to a fixed array. int A[1000]; int size=1000; int top; int front; int rear; bool StackIsEmpty() { return (top==0); } bool StackPush( int x ) { if ( top >= size ) return false; A[top++] = x; return true; } int StackTop( ) { return A[top-1]; } bool StackPop() { if ( top <= 0 ) return false; A[--top] = 0; return true; } bool QueueIsEmpty() { return (front==rear); } bool QueuePush( int x ) { if ( rear >= size ) return false; A[rear++] = x; return true; } int QueueFront( ) { return A[front]; } bool QueuePop() { if ( front >= rear ) return false; A[front++] = 0; return true; } It is presumed(or obvious) that the bottom of the stack and the front of the queue is pointing at the same location, and vice versa(top of the stack points the same location as rear of the queue). For example, integer 1 and 2 is inside an array in order of writing. And if I call StackPop(), the integer 2 will be popped out, and if I call QueuePop(), the integer 1 will be popped out. My problem is that I don't know what happens if I do both stack and queue operations on the same array. The example above is easy to work out, because there are only two values involved. But what if there are more than 2 values involved? For example, if I call StackPush(1); QueuePush(2); QueuePush(4); StackPop(); StackPush(5); QueuePop(); what values will be returned in the order of bottom(front) from the final array? I know that if I code a program, I would receive a quick answer. But the reason I'm asking this is because I want to hear a logical explanations from a human being, not a computer.
