Python has an eval() function that can do this: a = “https://stackoverflow.com/” b = “6” c = “3” print eval(b + a + c) However, please note that if you’re getting input from a remote source (like over a network), then passing such code to eval() is potentially very dangerous. It would allow network users … Read more
This can be a start. This checks whether the number N is divisible by all numbers from 2 to int(sqrt(N)) + 1, where the int function truncates the square root of N. The all() function in python returns True if all members of a list satisfy some condition (here not zero). You should set an … Read more
Build a regexp like this : .+?(r).* where r is you regexp. Java Code String s;// Your string String r;// Your regexp Pattern p = Pattern.compile(String.format(“.+?(%s).*”,r)); Matcher m = p.matcher(s); if (m.find()) { System.out.println(m.group(1)); } Note I assume your regexp will be matched only one time in your string s. 1 solved How do you … Read more

In my opinion two options are available on the table! 1.Create your AsyncTask class as an inner class inside your Activity class, and then you can gain access for all super class properties. public class MyActivity extends Activity { int property1; void method1() { } private class MyTask extents AsyncTask<Void, Void, Void> { @Override protected … Read more
In your code, int l= arr[0].length; in this line, arr[0] represents the value in array named as arr at 0th index. Hence length function can be used in this way to find the length of value stored in array at 0th index. int l = arr[0].length(); In order to find out the length of array, … Read more
int x=0; while(x<6) { int a;format output. int m = Hrand();value in int m. Balls[x] = m; because of an error. a = Balls[x]; cout<<“[“<<setfill(‘0’)<<setw(02)<<a<<“]”; x++; } Here, I also fixed a bug. Since Balls has 6 elements, the last element will be 5. Thus you want x<6 instead of x<=6. That goes for the … Read more
C++11 introduces the new header system_error for low level errors. It is possible to write your own error categories. This might be good starting point for writing your own error handling in modern C++. 7 solved c++ std::exception … may I have more please? [closed]
Here is one approach. I created new lat for text annotation using transform in base R. I used geom_text to add the labels you wanted. I used scale_colour_discrete to change the name of the legend. library(ggmap) library(ggplot2) ### Get a map map <- get_map(location=c(lon=34.832, lat=0.852), color=”color”, source=”google”, maptype=”terrain”, zoom=9) ### Create new lat for annotation … Read more
Turns out the phrase I was looking for was “list slicing”. And I get proper access to the data using group[[i]] solved How do I gain programmatic access to names in R?
Yes, exactly. In several version iOS, Android ( old), history.back() seem not working. To fix it, you should try this code ( i find it in JQM @@ and it working well for all ) var nav = window.navigator; if( this.phonegapNavigationEnabled && nav && nav.app && nav.app.backHistory ){ nav.app.backHistory(); } else { window.history.back(); } solved … Read more
The ForeColor of the GroupBox is not related to the Form ForeColor. Many controls do but GroupBoxes do not take the Form ForeColor. You should change GroupBox ForeColor if you want it to be yellow. 4 solved Setting color of the text property of GroupBox
Check out a working example in CODEPEN, looking in to the link provided by Enkode. Here I created a self-calling loop which can go as much as you specify, 100 in this case. $(“.clickButton”).click(function() { var counter = 0; var timeDelay = 10; // in millisecond var endCount= 100; // end of loop (function loopFunc … Read more
