The previous section describes the basic knowledge of using DFT to estimate power spectra, and this section discusses some specific issues. How to gain gains with DFT. In general, there are two ways: correlation gain and cumulative gain. The gain is

Problem STime limit:1000 MS Memory limit:32 MB 64bit IO Format:%i64dsubmitted:61 accepted:25[Submit] [Status] [Web Board]Description Given a positive integer N, you should output the leftmost digit of n^n. Input The input contains several test cases.

First look at the properties of logarithms, Loga (b^c) =c*loga (b), Loga (b*c) =loga (b) +loga (c); Suppose given a number of 10234432, then log10 (10234432) =log10 (1.0234432*10^7) =log10 (1.0234432) +7; LOG10 (1.0234432) is the small part of log1
