Index $$4 \rightarrow F_{3} = 1$$, $$j$$ satisfies while loop condition but $$Z_j = Z_i$$, hence does not go into while loop, therefore value of $$F_i = 2$$. The scoring of DevOps questions is done by the following method: Each candidate's submission is auto-evaluated against the added validation script. Question types include MCQs, programming, Java project, Diagram etc. One obvious and easy to code solution that comes to mind is this: For each index of $$T$$, take it as a starting point and find if $$T_{i,i+1,,i+|P|-1}$$ is equal to $$P$$. If this suffix also doesn't satisfy our criteria, then smaller suffixes can be found with the same process, here it will be $$F_{F_{F_i-1} - 1}$$. A & C (Both correct choices) 5.

If Marichka's happiness before traversing some road was X and road's happiness points are Y, then after traversing it Marichka's happiness will be equal to X xor Y. Marichka can traverse one road many times. The only thing remaining is, how to find the length of next smaller suffix ending at index $$i$$, that is also a prefix? It is to be noted that, value of $$F_{i+1}$$ can be at most 1 greater than $$F_i$$. So to find the next smaller suffix ending at index $$i$$, the longest suffix ending at $$F_i - 1$$ can be found which is $$F_{F_i-1}$$, and this suffix will be the next smaller suffix ending at index $$i$$.
