std::deque（両端キュー）は、先頭と末尾の両方で高速挿入と削除を可能にするインデックス付きシーケンスコンテナです。また、両端のどちらかの端に挿入したり削除すると、残りの要素へのポインタや参照を無効決して.
Original:
std::deque (double-ended queue) is an indexed sequence container that allows fast insertion and deletion at both the beginning and the end. In addition, insertion and deletion at either end of a deque never invalidates pointers or references to the rest of the elements.

std::vectorとは対照的に、両端キューの要素が連続して格納されていません：典型的な実装は、個別に割り当てられた固定サイズの配列のシーケンスを使用し.
Original:
As opposed to std::vector, the elements of a deque are not stored contiguously: typical implementations use a sequence of individually allocated fixed-size arrays.

dequeのストレージは自動的に展開され、必要に応じて収縮する。それが新しいメモリ位置への既存の要素のコピーを伴わないためdequeの拡大はstd::vectorの拡大よりも安いです.
Original:
The storage of the deque is automatically expanded and contracted as needed. Expansion of a deque is cheaper than the expansion of a std::vector because it does not involve copying of the existing elements to a new memory location.
