show how to implement 2 stacks in one array using java-like pseudocode. your stack routines should not declare an overflow unless every slot in the array is used.

to change your username, you must:

1) make sure what the username you want to change to is allowed in this community

2) contact a administrator (for example, jaysl)

3) through pm, tell the admin what you want to change to

4) if the username is allowed, it will be changed in a matter of seconds (minutes at most)
