How do you remove a last object from an NSMutableArray in Xcode? I can't find the right documentation.

Here is my earlier code that is okay and passed except for the last line which I know makes no sense but I am just grasping at straws now....

mutablearray.mm 
 NSMutableArray *elements = [NSMutableArray array];
 [elements insertObject:@"Helium" atIndex:0];
 [elements insertObject:@"Neon" atIndex:1];
 [elements insertObject:@"Argon" atIndex:2];
  [elements removeObjectAtIndex:1];
  NSMutuableArray *elements = [elements removeLastObjec];

Actually I just figured it out. In case anyone else has the same problem:

[elements removeLastObject];
