A map, sometimes referred to as a dictionary, consists of a key/value pair. The key is used to order the sequence, and the value is somehow associated with that key. For example, a map might contain keys representing every unique word in a text and values representing the number of times that word appears in the text.
Lookup, find, or get find the value (if any) that is bound to a given key. The argument to this operation is the key, and the value is returned from the operation. If no value is found, some lookup functions raise an exception, while others return a default value (such as zero, null, or a specific value passed to the constructor).
find_character(string,char) returns integer Description Returns the position of the start of the first occurrence of the character char in string. If the character is not found most of these routines return an invalid index value – -1 where indexes are 0-based, 0 where they are 1-based – or some value to be interpreted as Boolean FALSE.
Here's how to ensure that communities, families, and young girls can find the mental health care they need without judgment or unnecessary barriers: Develop community-based screening and care ...
A dictionary coder, also sometimes known as a substitution coder, is a class of lossless data compression algorithms which operate by searching for matches between the text to be compressed and a set of strings contained in a data structure (called the 'dictionary') maintained by the encoder. When the encoder finds such a match, it substitutes ...

A study in the Journal of Child Psychology and Psychiatry found that decades of lead exposure has resulted in mental health challenges for generations of Americans.
A common programming task is to remove all elements that have a certain value or fulfill a certain criterion from a collection. In C++, this can be achieved using a hand-written loop. It is, however, preferable to use an algorithm from the C++ Standard Library for such tasks. [1] [2] [3]
