Virtual Gate Test Series: Algorithms - Order Of The Algorithm
An algorithm is made up of $2$ modules $M_{1}$ and $M_{2}.$ If order of $M_{1}$ is $f(n)$ and $M_{2}$ is $g(n)$ then the order of the algorithm is$:$ $\text{max (f (n) ,g (n))}$ $\text{min (f (n) ,g (n))}$ $\text{f (n) + g (n)}$ $\text{f (n) $\times$ g (n )}$

Virtual Gate Test Series: Databases - Recover Schedule
Assume there are n transactions$:T_{1},T_{2},.,T_{n}.$ Every transaction writes value of $X$ that is read by its successive transaction like $T_{1}$ writes value of $X$ that is read by $T_{2}, T_{2}$ writes a value of ... $X$ that is read by Tn. Now,if $T_{1}$ fails,then total how many transaction rollbacks are required to recover the schedule?
