Upper Bound

Upper Bound Upper bound finds the first index at which elements become strictly greater than a value $x$. It returns the smallest index $i$ such that $$ A[i] > x $$ If no such index exists, it returns $n$. This operation complements lower bound and allows precise range queries over equal values. Problem Given a sorted array $A$ of length $n$ and a value $x$, find the smallest index $i$...
