In this mission, the hacker has to access a file containing 2 values and copy them in the reverse order to a new file in the outbox before destroying the original.
With the REPL command it's possible to do this with one EXA module with an increase in size by 1 and a reduction in activity by 1. But the point is to learn how to use multiple EXA units.
| Solution | Cycles | Size | Activity | EXA Modules |
|---|---|---|---|---|
| 01 | 10 | 14 | 4 | XA XB |
| 02 | 9 | 13 | 4 | XA XB XC |
