If anyone knows logic behind how to solve it please give solution.
Refer to the above. As far as I remember, the logic behind the solutions were such: for poetic word, modelling it as max flow/min cut solves the problem.
For nested candy boxes, it was a compression problem where you had to note that 2^x can be greater than 10^{12} pretty quickly.
I fear I cannot be of any help here
