Solution

The sequence of operations performed on the stack are as follows:

  1. push(6): The stack now contains 6.
  2. push(7): The stack now contains 7, 6.
  3. pop: The operation removes 7 from the stack. The popped value is 7.
  4. push(5): The stack now contains 5, 6.
  5. push(4): The stack now contains 4, 5, 6.
  6. pop: The operation removes 4 from the stack. The popped value is 4.
  7. pop: The operation removes 5 from the stack. The popped value is 5.
  8. pop: The operation removes 6 from the stack. The popped value is 6.
  9. push(3): The stack now contains 3.
  10. pop: The operation removes 3 from the stack. The popped value is 3.

So, the sequence of popped out values are 7, 4, 5, 6, 3. Therefore, the correct answer is "7,4,5,6,3".
