Print BST keys in the given range

though its a bst question i am using the concept of sorted arrays but still its showing wrong output.

Consider input:
1
10
14 17 7 18 12 5 4 6 21 24
11 17

Expected o/p:
# Preorder : 14 7 5 4 6 12 17 18 21 24
# Nodes within range are : 12 14 17

Your o/p:
# Preorder : 12 5 4 6 7 18 14 17 21 24 
# Nodes within range are : 12 14 17
