The program must accept N integer values and print the values which are equal to the count of their occurrence (in ascending order). If there is no such value then the program must print -1.
Boundary Condition(s):
1 <= N <= 100
1 <= Each integer value <= 100
Input Format:
The first line contains N.
The second line contains the N integer values separated by a space.
Output Format:
The first line contains the integer values separated by a space.
Example Input/Output 1:
Input:
4
2 4 2 3
Output:
2
Example Input/Output 2:
Input:
11
2 1 4 3 4 3 4 5 3 4 6
Output:
1 3 4
