Approach 1ddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd

  • You can traverse the tree in in-order way, and see if the elements are assending.
    • You may either put the elements into an array and see if the array is sorted in assending way,
    • or while traversing see if the current element is always greater than or equal to previous element.
      • return false is current data is less than previously printed data.
      • may use a static variable to hold the last printed value.
