要素の最初の部分
[s_first, s_last)
範囲[first, last - (s_last - s_first))
内を検索します。最初のバージョンは、要素を比較するoperator==
使用して、2番目のバージョンは、指定されたバイナリ述語p
を使用しています.Original:
Searches for the first subsequence of elements
[s_first, s_last)
in the range [first, last - (s_last - s_first))
. The first version uses operator==
to compare the elements, the second version uses the given binary predicate p

first, last | - | 検討する要素の範囲 Original: the range of elements to examine The text has been machine-translated via Google Translate. You can help to correct and verify the translation. Click here for instructions. |
s_first, s_last | - | 検索する要素の範囲 Original: the range of elements to search for The text has been machine-translated via Google Translate. You can help to correct and verify the translation. Click here for instructions. |
p | - | binary predicate which returns true if the elements should be treated as equal. The signature of the predicate function should be equivalent to the following: bool pred(const Type1 &a, const Type2 &b); The signature does not need to have const&, but the function must not modify the objects passed to it. |
