In iOS development, we often encounter the problem of view setting fillet, if we need to uiview 4 corners all rounded, it is quite simple, just set the Cornerradius property of its layer (the project needs to use the Quartzcore framework). This method is not good when you want to specify a few corners (less than 4) to
{for (j=0;j{if (*getelementpoint (p,i,j) {Min=getelementpoint (P,I,J);}}}Interchange minimum and bottom right position elementsSwap (min, (p+n*n-1));}void Main (){int arr[n][n];int i,j,*p = arr[0]; Note that P is a row pointer, and initialization points to the first rowvoid (*f) (int *p);f = specialsort; F is a function pointer pointing to the Specialsort functionprintf ("Please input a%d*%d matrix:\n", n,n);for (i=0;i{for (j=0;j{scanf ("%d", arr[i][j]);}}(*f) (p); Calling the Specialsort
In the previous article, we learned the surface removal and cropping modes.
This article will use this knowledge to implement a simple, but not frequently used example: make an image into a rounded rectangle
Example 3: shader with rounded corners
Well, I admit that I had taken a lot of detours in this example, because I have completely mastered the matrix and returned it to the teacher, so I started to use some stupid methods to calculate the rounded
This example describes the PHP method for calculating the maximum minimum latitude and longitude of 4 corners in the current coordinates of 3 km. Share to everyone for your reference, as follows:
$LNG, $lat latitude and longitude $half = 6371; $distance = 3; 3 km $DLNG = 2 * ASIN (SIN ($distance/(2 * $half))/cos (Deg2rad ($lat))); $DLNG = Rad2deg ($DLNG); $dlat = $distance/$half; $dla

Java study NOTE 4: Several corners of static and small talk about polymorphism, learning notes static
There are a few things recently. If you haven't updated your notes in time, you can't discard your studies. To sum up the recent studies, the focus is on some static applications. polymorphism is a design concept that is easy to understand, it is not easy to think about it.
For static, there are two mai
This article describes the method for PHP to calculate the maximum minimum latitude and longitude of 4 corners within 3 km of the current coordinates. Share to everyone for your reference, specific as follows:
$LNG, $lat latitude and longitude
$half = 6371;
$distance = 3; 3 km
$DLNG = 2 * ASIN (SIN ($distance/(2 * $half))/cos (Deg2rad ($lat)));
$DLNG = Rad2deg ($DLNG);
$dlat = $dis
