HI @Adi_choudhary,
Here is the view of tree in other view
2 => 1 <= 3
4 => 2 <= 5
-1 => 4 <= -1
END => -1 <= END
END => -1 <= END
-1 => 5 <= -1
END => -1 <= END
END => -1 <= END
6 => 3 <= -1
-1 => 6 <= -1
END => -1 <= END
END => -1 <= END
END => -1 <= END
How actually your doubt is correct both 5 and 6 are overlapping so in such overlap cases we take the one which comes later while traversal … So in our case 5 will come before 6 while traversal so we take 6 in bottom view.
