hello @garganshul151

this is not correct .
because here u will sort only f array without changing s.
but because f and s are related ,sorting of f should also change s.

read them as pairs and then sort that pairs.

also tell why greedy approach is necessary here and why we cant do without sorting?

#6

why r u using array after sorting vector of pairs?
use pairs only for ur furthur algorithm.
u logic is correct. just u need to use pair.
