  • cf702A Maximum Increase

    A. Maximum Increase
    time limit per test 1 second
    memory limit per test 256 megabytes
    input standard input
    output standard output

    You are given array consisting of n integers. Your task is to find the maximum length of an increasing subarray of the given array.

    A subarray is the sequence of consecutive elements of the array. Subarray is called increasing if each element of this subarray strictly greater than previous.

    Input

    The first line contains single positive integer n (1 ≤ n ≤ 105) — the number of integers.

    The second line contains n positive integers a1, a2, ..., an (1 ≤ ai ≤ 109).

    Output

    Print the maximum length of an increasing subarray of the given array.

    Examples

    真是逗逼。。写了<和>的情况忘记搞=了

    然后被x。。

    幸好不记分

    哎毕竟是老了
