Data structures used:
Algorithm:
Insert it as key & increase frequencies. (0 ->1)
For same key it will only increase frequencies.
Set an iterator to hash.begin().
iterator->first is the key (array element) & iterator->second is the value( frequency of corresponding array value)
Time complexity: O(n)
Explanation with example:
For this array: 2 5 3 2 4 5 3 6 7 3
The code:
Actually does the following
Thus, Elements with frequency 1 are: 7, 6, 4
C++ implementation to print all the Non-Repeated Numbers with Frequency in an Array
