Umil Bolt is an excellent runner. His specialty is the 100-meter race. Every day, he makes a battery of attempts to run this test in an ever faster time. It can be seen that, depending on the number of attempts, its performance improves or worsens. About this, he asks for your help to calculate the fastest attempt of each daily battery.

Input

The input is composed of several test cases. The first line of each test case contains an integer T (2 <= T <= 99) relative to the number of trials of a day. The following T lines contain a real number Ti (9 <= Ti <= 11) relative to the time, in seconds, of the ith battery attempt. The entry ends with end of file.
