Sir pls tell whats the error in this code

#1

i was trying the question to build tree from inorder and postorder traversals and then write preorder traversal of tree…
here is my code-

#2

the code is perfectly fine
when u run each case individually the o/p is correct
and in case of multiple test cases theere are a lot of garbage value
might be so that it depends on what memory locations are used to make the tree

doing it this way without taking test cases still works fine

#3

in short u do not have to worry ur code is fine
its just that multiple test cases cause a problem

#4

maam but how do i run the code… this question is from hacker blocks and they require multiple test cases… how do i make it running perfectly for multiple test cases

#5

bro share hackerblock link for this question

#9

maam pls suggest changes to be done in my code to make it clear the test case

#10

simply copying code from geeks and geeks would not help me build my understanding…
