[2,1,1] test case gives the wrong expected answer

  • 0

    I was trying the test case [2,1,1]. The expected output given by the system is 1.
    This should be corrected as the expected value should be 2.

    [2,1,1] is invalid input, if you meant, 2 is root, 1 is left child and another 1 as right child

    In that case, 1 would be the root
