Hi @dakshi
upper_bound() function in C++ that returns an iterator pointing to the first element in the range [first, last) that is greater than value, or last if no such element is found. One thing to note in dis is that array should already be sorted.
so index=upper_bound(a,a+n,money) makes the index point to the first location with value greater than money.
similarly
lower_bound() function in C++ that returns an iterator pointing to the first element in the range [first, last) that is equal to the value(if not equal to any element ponts to first element greater than the value) One thing to note in dis is that array should already be sorted.
Hope dis helps.
