In this article, we learned how to remove an element from a Bash array. Furthermore,we solved the use case using the concept of positional offsets, the selective-copying technique, and utilities such asset,shift, andtac.
166: //When an element of a container is erased, all iterators that point to that 167: //element are invalidated. Once c.erase(it) reuturns, it has been invalidated. 168: template <typename Cont, typename Pred> 169: inline void erase_if_helper(Cont& c, Pred p, associative_like_tag)...
