In such sequences the aforementioned operations are more interesting and useful than binary_search. The addition of these three ops will complement the support of sorted slices in the standard library. Proposed APIs lower_bound /// Finds the first element in the sorted slice that is _not less...

Lower bound(L(n))is a property of the specific problem i.e. the sorting problem, matrix multiplication not of any particular algorithm solving that problem. Lower bound theorysays that no algorithm can do the job in fewer than that of(L (n))times the units for arbitrary inputs i.e. ...
