 # VARIABLE DESCRIPTION
 ## R : Roman numeral
 ## C : "Checkpoint", hardcoded values where the "pattern" for roman numerals changes
 ## n : Local variable for N
 ## D2R : Function that finds the number of occurances (F) of a checkpoint in a given number and prints it F times , for example, D2R(34,10,X) gives the answer as XXX as F = 3
 ## F : No. of occurances of a checkpoint in N
 ## K and V : (Key and Value) Decimal to Roman mapping for the checkpoints
