@Aditya-Kushwaha-914550392281281 hey 1+subproblem is there because,we have already use one coin and asking remaining number to find your ans through recursion,suppose 15 total hai 1,4,7 coins hai to 15 me se 1 use krlia to 14 ko hm bolenge ki tu apna answer lakr de and hmne ek 1 ka coin already use krlia hai tabhi 14 bacha hai so 1 is added for that 1+ 14 subproblrm answer.
