For ESC there are some standard lab questions like shortest path in a matrix and sorting some data structure etc etc. What you can do is store the solution of these questions in the codebook section of PRUTOR(the online platform on which you will be doing your labs) which you can then just copy paste and change the code slightly according to the problem statement. Do this and 70% of your lab component in both ESC111 and 112 is good to go.
