Mode Value

Your task is to write a program which reads a sequence of integers and prints mode values of the sequence. The mode value is the element which occurs most frequently.

Input

A sequence of integers ai (1 ≤ ai ≤ 100). The number of integers is less than or equals to 100.

Output

Print the mode values. If there are several mode values, print them in ascending order.

Example

Input

5 6 3 5 8 7 5 3 9 7 3 4

Output

3 5
