@atul zig-zag mean spiral traversal of tree e.g. alternate the level while traversing , if previous traversal is left to right , then next level will be right to left .
@aman .quest has little ambiguity its says successor but ebvery nodes can have we can ore-order , inorder ,postorder successor isn't it ?? but i am assuming u r interesting in pre-order succesor so then 1st find the per-order successor of each node & then set it , finally traverse it ? correct me if i am wrong ?
