The counting pattern is a fundamental technique used in programming to solve problems that involve counting occurrences, frequencies, or specific properties within a data set. This pattern is particularly useful when you need to track the number of times elements appear or when certain constraints depend on the frequency of elements. It often involves using data structures like hash maps, arrays, or sets to efficiently count and manage occurrences.

Counting is widely applied in problems such as finding the majority element in an array, checking for anagrams, or detecting duplicates.
