Let us create binary tree given in the above example
root = newNode ( 1 ) NEW_LINE root . left = newNode ( 2 ) NEW_LINE root . right = newNode ( 3 ) NEW_LINE root . left . left = newNode ( 4 ) NEW_LINE root . left . right = newNode ( 5 ) NEW_LINE root . right . left = newNode ( 6 ) NEW_LINE root . right . right = newNode ( 7 ) NEW_LINE root . right . left . right = newNode ( 8 ) NEW_LINE print ( " Nodes ▁ at ▁ distance ▁ 2 ▁ are : " , end = " ▁ " ) NEW_LINE printKDistantfromLeaf ( root , 2 ) NEW_LINE
