What does the following pseudocode axiom mean, in English?

1. ( aStack.push( item ) ).pop() = aStack

2. aList.getLength() = ( aList.insert( i, item ) ).getLength() - 1

3. ( aList.insert( i, item ) ).remove( i ) = aList

4. aList.getEntry( i ) = ( aList.insert( i, item ) ).getEntry( i+1 )

Expert Solution

Please let me know in case of any issue

1. ( aStack.push( item ) ).pop() = aStack
pishing an item in stack and then removing, it means stack came in same state as it was before these two operation

2. aList.getLength() = ( aList.insert( i, item ) ).getLength() - 1

length of list = length if list that has one more element - 1

3. ( aList.insert( i, item ) ).remove( i ) = aList
   Adding an item at index i, then removing same item, that means list has same set of elements as
   it was before these two operation
4. aList.getEntry( i ) = ( aList.insert( i, item ) ).getEntry( i+1 )

       aList.getEntry( i ) =>getting an elemets at index i
       aList.insert( i, item ) => insert an item at i
       ( aList.insert( i, item ) ).getEntry( i+1 ) => inserting an item at index i and then getting elemnts from index (i+1)
