Question

The Oasis animals get to know about the

coronavirus pandemic from a nearby village.

They visit the village to check the situation.

They find that the fight against the deadly

coronavirus has come to a final showdown.

All the virus in the world has been swept

away, except one. However, the bad news is

that this final virus has mutated to the level

where one can never kill it, but only trap it

forever. The villagers have successfully

trapped the virus in a 5x5 maze (each block

=1 cmx1cm) from which they cannot afford

to let it escape. The virus resides at the

centre of the block and can only move from centre of one block to another block. The

virus has developed a function according to

which you need to introduce it ton

chemicals.. which will denote the

distance (in cm) it can move in a turn. The

numbering of each chemical denotes the

distance the virus must travel in a particular

minute and the number on each chemical

must be distinct.

The chemical to be used is decided by the

virus and the direction of movement is

decided by us (not necessarily horizontal or

vertical). We need to create a set of numbers with max possible numbers of

elements, S, such that no matter which

number the virus chooses from that set, we

can make sure it doesn't escape the maze

ever.

Each minute the virus will be positive for a

particular chemical (this is random, the

villagers have got no control over it), and

they must move it to another block, the

distance corresponding to the chemical.

What is the max value of n and what are

the n chemicals i.e. the distances induced by

these chemicals(in cm) that one must choose, given that the virus begins at the

top left room? State your answer as the sum

of the chemical numbers of set S. If it's

impossible to find such n chemicals, state

the answer as 0.

Note(all distances moved must always be integral)​
