These are part $1$ and part $2$ of the same question, it requires the usage of previous code.

Add the function to a PyDev module named

functions.py$.$ Test it from

t$01.$py $.$

Sample result $($values are listed top to bottom$)$:

Write and test the following method that extends the Stack class:

def combine$($self$,$ source$1,$ source$2)$:

$"$n$"$

Combines two source stacks into the current target stack.

When finished, the contents of source $1$ and source $2$ are interlaced

into target and source$1$ and source $2$ are empty.

Use: target.combine$($source$1,$ source$2)$

Parameters:

source$1-$ an array$-$based stack $($Stack$)$

source$2-$ an array$-$based stack $($Stack$)$

Returns:

None

Add this method to the PyDev module Stack$\_$array.py in your login$\_$data$\_$structures project. Test it from

t$02.$py$.$

that the Use example is different than that of the previous Task.

Hint: if your code for the previous Task and this Task are identical, you're doing it wrong. However, the sample results should be the same as for the previous Task.
