The goal of this article: let the small partners not very understand DSP will use FFT (Fast Fourier transform), and know how to use the code to achieve FFT, superficial understanding, but for works.
Recently did the project to use the FFT, previously learned is not very clear, now used to make a decision to understand it well. In the Chinese website to find some information, found that the said is n
, which represents the balance on the card. mN=0 indicates the end of the data.Output for each set of inputs, outputs a line that contains an integer that represents the smallest possible balance on the card.Sample Input
1 50 5 10 1 2 3 2 1 1 2 3 2 1 50 0
Sample Output
-45 32
In fact, the two-dimensional DP equation should be Dp[i][j]=max (Dp[i-1][j],dp[i-1][j-

I believe that when you use Linux, you have encountered accidental deletion of file system data, whether it is accidental deletion or recovery of accidental deletion.
Currently, many recovery tools are usually ext3grep and extundelete.

For example, an array of char P [5]. If P [0] = '0',

5. There are 3 timer 0 and 4 timer 1 correspond to the external output of the matching register. The output of matching is as follows:
Set to low when matching
Set to high when matching
Flip When matching
No action during Matching
6. For each timer, up to four matching registers can be configured as PWM, and up to three matching outputs can be use
those variables are put into rom/flash. Sometimes these initial values are larger, and Keil will compress these initial values into Rom/flash to save storage space. So who are these initial values when they are restored to ram? Zi the variables in the input section are in RAM and who is initialized with 0? To understand these things, look at the default settings, from the system reset, to the execution of the C code you write the main function, Keil
1. starting Python from IdieIdle is a python shell,shell meaning "shell", which is basically a way of interacting with the program by entering it. Windows like the cmd window, like the Black Command window of Linux, are all shells and can be used to give commands to the operating system. Similarly, you can use the idle shell to interact with the Pytho. >>> This prompt means: Python is ready, waiting for the Python command to be entered;baishuchaodemacbook-pro:~ xcn$ Python3.5python 3.5.2rc1 (V3.
