Idea is to swap Binary tree's element's with it's left node. Here's the code I came up with:

when I print elements, Elements left to node are swapped but not right....please help in fixing this.Code:TREE swap_left (TREE T){ element_type tmp; if(T!=NULL){ if(T->left){ tmp = T->element; T->element = T->left->element; T->left->element = tmp; T = T->left; } return (swap_left(T->right)&& swap_left(T->left)); } return T; }
