You can use pandas: import pandas as pd l = [-1.5,-1,-1,0,0,-1,0,1.5,1,1,1,1,0,0,0,0,1,0,1,0,1.5,1,1,1,1,0,0,0,0,-1.5] s = pd.Series(l) cond1 = (s == 1.5) cond2 = (s == -1.5) cond3 = (s == 0) cond4 = ((s == 1) | (s == -1)) & (s.shift() == 0) out = pd.Series(pd.np.select([cond1, cond2, cond3, cond4],[1, -1, 0 ,0], pd.np.nan)).ffill() out.tolist() Output: [-1.0, … Read more

I was able to locate where gccgo is asking for so much memory. It’s in the libgo/go/runtime/malloc.go file in the mallocinit function: // If we fail to allocate, try again with a smaller arena. // This is necessary on Android L where we share a process // with ART, which reserves virtual memory aggressively. // … Read more
In my opinion this can be done only with global hook. But global hook is not supported by .NET, take a look at this answer. So you can’t do this with VB.NET but can with C++. EDIT: you can do this with VB.NET or any other .NET language, see comments for pointers. 5 solved How … Read more
The dot (.) is the concatenation operator in Perl. $string = $a_substring . $another_substring; Sometimes you want to concatenate text to the same variable. $string = $string . $some_extra_text; Most binary operators in Perl have an “assignment” version which simplifies code like this. So instead of: $total = $total + $line_value; You can just write: … Read more
Here is the sample code *> char[] arr = new char[50]; int i = 0; private void richTextBox1_KeyUp(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Space) { string str = new string(arr); MessageBox.Show(str); Array.Clear(arr, 0, arr.Length); i = 0; } else if (e.KeyCode == Keys.Back) { i–; if (i < 0) { i = 0; … Read more
If you insist on shared preference use this code : To save the data private void saveSp(String key , String value){ PreferenceManager.getDefaultSharedPreferences(Context) .edit() .putString(key, value).apply(); } To get your data: PreferenceManager.getDefaultSharedPreferences(Context).getString(“string”, “default”) solved How to use shared preference to send data from activity to fragment?
I had to discern what you’re looking for not only from your question, but also from your comments. It looks like every string begins with ‘f’, and each empty bracket-pair appends an ‘o’. Finally, a non-empty bracket-pair appends its argument. I actually think this is a cool metaprogramming challenge. This should work: let f = … Read more
all you have to do is correct the %l(there is not such a specifier), you probably should have used %ld. char *buildStatus() { struct rusage *usage = malloc(sizeof(struct rusage)); int usageRet = getrusage(RUSAGE_SELF, usage); if (usageRet == -1) { perror(“RUSAGE fail”); exit(EXIT_FAILURE); } long unsigned cpuTime = (usage->ru_utime).tv_sec + (usage->ru_stime).tv_sec; long memUsed = get_memory_usage_linux(); unsigned … Read more
Sounds like by “the last part”, you mean “the part before the query string or after the last slash if there’s no query string”, right? Well, you can find the bit after the last slash with this: /([^\/]+)$/ And you can find the bit between a slash and the first question mark like this: /([^\/]+)\?/. … Read more
Works for me void resize(double *&a, int oldSize, int newSize) { double *a1 = new double[newSize](); if (newSize > oldSize) { for (unsigned i = 0; i < oldSize; i++) { a1[i] = a[i]; } } else if(oldSize > newSize) { for (unsigned i = 0; i < newSize; i++) { a1[i] = a[oldSize – … Read more
You don’t need to pass category_name, you only need the category id. The category name should be contained in each of the item fetched from the database. You’re getting an error because cat_id is not defined when the function def getCategoryItems(category_name, cat_id) is called. I would suggest, however, if you want to really get all … Read more
You can use like this (netstat is only dummy command. you can write whatever you want) ; String command = “cmd.exe /c start ” + “netstat”; Process child = Runtime.getRuntime().exec(command); after that you can get as data stream from child process. Or you can close the cmd also with child.destroy() method forexample. 1 solved How … Read more
