find()方法用於查找滿足給定謂詞的SortedMap的第一個元素。 函數定義:def find(p: ((A, B)) => Boolean): Option[(A, B)] 返回類型:It returns the first element of the SortedMap which satisfies the given predicate. 範例1: // Scala program offind()// methodimportscala.collection.immutable.So...
sortedmap_Name.find(condition) Parameters The method accepts a condition. Return Type It returns an element that satisfies the given condition.

unique in thestd::mapcontainer. Thus, if new elements are inserted with the existing keys, the operation does not have any effect. Still, some special member functions in thestd::mapclass can assign new values to the existing pairs if the keys are matched (e.g.insert_or_assignfunction)....
