Mode

A sequence A1, A2, ..., AN of length N is given. Each term of this sequence is an integer between 1 and M, inclusive.

Define a new sequence B1, B2, ..., BM of length M as follows.

• For each j (1 ≦ j ≦ M), the value of Bj equals the number of integers i (1 ≦ i ≦ N) such that Ai = j.

Find the maximum value among B1, B2, ..., BM.

The input is given from standard input in the following format.

N M
A1 A2 … AN

Print the maximum value among B1, B2, ..., BM on one line.

• 1 ≦ N ≦ 100.
• 1 ≦ M ≦ 100.
• 1 ≦ Ai ≦ M (1 ≦ i ≦ N).
