Calculates the solution which is circular.

The numbering starts from one, i.e., if A = [3, 1, -1, 2] then FindKthLargest(1, A) returns 3, FindKthLargest(2, A) returns 2, FindKthLargest(3, A) re

Input nodes are nonempty and the key at s is less than or equal to that at b.

Input nodes are nonempty and the key at s is less than or equal to that at b.

Calculates the non-circular solution.

Insert new_node after node.

Insert new_node after node.

Each entry in previous_attempts is a point in the grid and suffix of pattern (identified by its offset). Presence in previous_attempts indicates the s

Test if a newly placed queen will conflict any earlier queens placed before.

Returns an object consisting of an int and a node. The int field is 0, 1, or 2 depending on how many of {node0, node1} are present in the tree. If bot

Computes the nodes from the root to the leftmost leaf.
