When inserting a key-value pair into a left-leaning red-black BST, which of the followin properties must the binary tree have immediately after a call to rotateLeft()? Mark all that apply. The inorder traversal of the tree yields the keys in ascending order. Every path from the root to a null link has the same number of black links. At least one left link in the tree is colored red. No two left-leaning red links in a row. No right link in the tree is colored red.

Expert Solution
Step 1
A left-leaning red–black (LLRB) tree is a type of self balancing binary search tree. It is a variant of the red black tree and guarantees the same asymptotic complexity for operations, but is designed to be easier to implement.
Nodes which have double incoming edge are RED in color.
Nodes which have single incoming edge are BLACK in color.
