Answer:

Let the function be Node* ins(Node *root,int k)

if root node is NULL then return new node with data equal to k.

If the k <root->data

root->left=ins(root->left,k);

else if k >root->data

root->right =ins(root->right,k);

At last return root.

Explanation:

Make sure that you understand how addDigits( number, base ) works!

```
#!/usr/bin/python

import sys

def addDigits( number, base ):
    if( number ):
        return( addDigits( number // base, base ) + ( number % base ) )
    else:
        return( 0 )

def wrapper( number, base=10 ):
    if( ( addDigits( number, base ) ) % 2 ):
        return True
    else:
        return False

if( __name__ == "__main__" ):
    if( len( sys.argv ) != 2 ):
        sys.stderr.write( "usage: " + sys.argv[ 0 ] + " <integer>\n" )
        exit( 127 )

    print wrapper( int( sys.argv[ 1 ] ) )
```
