There are two important operations on a stack: PUSH and POP. PUSH adds the new data to the top of the stack leaving previous data below, and POP removes and returns the current top data of the stack. When the operations shown below are sequentially executed, which of the following is the correct
combination of the values x and y? Here, the size of the stack is big enough to hold the entire data. “PUSH(a)” inserts the data a into the stack, and “POP(b)” removes the data b from the stack.

1.0/ 1.0 Points
What can we do with the Circle symbol when drawing the flowchart to represent the algorithm?
A.Use it to represent a decision point in the process. Typically, the statement in the symbol will require a `yes' or `no' response and branch to different parts of the flowchart accordingly B.Use it to represent an event which occurs automatically. Such an event will trigger a subsequent action, for example `receive telephone call’, or describe a new state of affairs.
C.Use it to represent an event which is controlled within the process. Typically this will be a step or action which is taken. In most flowcharts this will be the most frequently used symbol D.Use it to represent a point at which the flowchart connects with another process. The name or reference for the other process should appear within the symbol
