Insert the specified `numElements` copies of the specified `value` into the array of type `allocator_traits<ALLOCATOR>::value_type` starting at the specified `toBegin` location, shifting forward the elements from `toBegin` to the specified `toEnd` location by `numElements` positions. If a (copy or move) constructor or a (copy or move) assignment operator throws an exception, any elements created after `toEnd` are destroyed and the elements in the range `[toBegin .. toEnd)]` are left in a valid but unspecified state. The behavior is undefined unless `toBegin` refers to space sufficient to hold at least `toEnd ‐ toBegin + numElements` elements.
