Problem in finding the lowerbound

#1

I wanted to ask that in the video bhaiya has used the statement:

int lb=lower_bound(coins,coins+n,key,compare)-coins-1;
so the above will return the index for 50 but it should be for the 100 pls clarify ; money=168

@jsn853
observe carefully you will get 100 for 168 here cause your lowerbound function will return 200 as answer then subtracting 1 from this will give you index of 100.
