1) you can assume we are using the immediate update protocol We saw that REDOs have to be done left to right i.e. earlier writes are redone first and then later writes. Give an example to show why it should be done this way by doing the following:

i. Find a simple example where it does make a difference whether the REDOs are done left to right or right to left.

ii. Show what the results will be if the REDOs are done left to right.

iii. Show what the results will be if the REDOs are done right to left.
