In the function move I computed the new coords and I checked if player has enough stamina to make the move. If an elf meets another one they will fight using the following condition: if an elf A fights and elf named B the hits needed to kill A are (A.hp + B.dmg - 1) / B.dmg and the hits needed to kill B are (B.hp + A.dmg - 1) / A.dmg so if A starts the hits needed to kill B remains (B.hp + A.dmg - 1) / A.dmg - 1. The winner is the one who needs fewer hits to kill the other one.

For snowstorm I extracted the data from that package and for all players alive on the glacier affected by the snowstorm I updated theirs hp.

To print the scoreboard I sorted indexes of elfs stored in an auxilliary array by required criteria (dry/wet, eliminated, lexicographically) with bubble sort.

For meltdown I reallocated memory to keep only the current glacier. Also I kept track of meltdown operations executed. For the others functions I took into account that indexes are shifted "meltdowns" positions to North-West.

I stored data in two structures, one for elfs and one for glacier. I allocated dinamically the elfs array, their names and the glacier bidimensional array. At the end of program I released all the memory used. For best precision I used distances squared, to keep the variables integers.
