text: Let us construct the tree given in the above diagram
code: struct node * root = newNode ( 20 ) ; root -> left = newNode ( 8 ) ; root -> left -> left = newNode ( 4 ) ; root -> left -> right = newNode ( 12 ) ; root -> left -> right -> left = newNode ( 10 ) ; root -> left -> right -> right = newNode ( 14 ) ; root -> right = newNode ( 22 ) ; root -> right -> right = newNode ( 25 ) ; printf ( " Size ▁ of ▁ the ▁ smallest ▁ vertex ▁ cover ▁ is ▁ % d ▁ " , vCover ( root ) ) ; return 0 ; }
