#6

Hi @hunt
if u still have any doubt, feel free to post it here

#7

hy @Yash_N
why this condition - letters[e]>target

#8

@hunt
we r using dis condition letters[e]>target in order to stop or while loop when let[e] becomes smaller than or equal to target the target.
u will see that we are using
ans=mid;
e=mid-1;
in else, hence when let[e] becomes<=target, we would have stored the greater element in ans.
hope dis helps.
