Problem

John is planning to plant trees in the city.The city is organized in such a way that only similar continuous blocks can be done within a given time. John has the information about the arrangement of blocks. Help him to calculate the maximum number of plants that he can able to complete within the given time

Given: First line of input contains N denoting number of blocks. Then for following N space separated number denotes type of block

Return: Output maximum number of plants that he can able to plant in blocks
