Bit operation only needs an instruction cycle to complete, and most of the C compiler "%" operation is to call subroutines to complete, the code is long, slow execution speed. In general, as long as the remainder of 2n square is sought, the method of bit operation can be used instead.
The last step is to pull request The first optimize: https://github.com/gurushida/qrcode/pull/2 The second optimize: https://github.com/gurushida/qrcode/pull/1 and wait for the response from author.
This is the third contribution I have made for Hacktoberfest. It is a rent web application with forms. The issue can be found here . When I looked at this application, I tried to finish some form. I am not familiar with this content. So I am not match all the requirement to finish the form. I received some hits. However, I have no idea which one is flat name and which one is base rent. Here is the pull request I have made. I add some text just before the input area. Those fixes are quite simple, However, it improve the users' experience a lot I think. I learned sometimes we should pay more attention to the user's experience.
This is the second contribution I have made for Hacktoberfest. It is a guess a number game. The issue can be found here . When I play this game, I found if I clicked the reset button, the difficult level come back to the default 1 to 100, but the radio option will stay at the previous one I chosen. Here is the pull request I have made. I add one line to set the radio option back to default, and also give the default option an id. Firstly, I searched on the website by how to reset the radio to default value. There are many way, more complicated than what I finally did. And I found the author try to do this things either. I even found the code he leaved as a common just as same as I tried. But those doesn't work. Then I went back to W3School to learn the radio button. I made it, quite simple:) I learned not always try to cut corners.
