Given a Singly Linked-List, implement a method to delete the node that contains the same data as the input data.
Example:
delete(1->2->3->4,3) ==> 1->2->4
class SinglyLinkedList:

Hi this is doing my head in. Sometimes functions I have in python (django) return a number and sometimes a nonetype (irrespective of cache period). It prints the cache in the method but the function still seems to return nonetype. Often the cache will not show in a print function but also do not ...

I'm a novice C programmer and would like some feedback on this function:
void strcpy_s(char *dest, const char *src) {

}
Did I overlook anything obvious?
Is this really a safe replacement for strcpy?

The 2018 Stack Overflow Developer Survey is open right now, and we on the Data Team are eagerly awaiting this year’s data so we can uncover new insights about the worldwide developer community. Every year, we learn interesting things, whether that’s about student developers’ attitudes toward industries or fictional representations of coders. I work remotely, along with the majority of the technical employees here at Stack Overflow, so before we have new survey data to explore, let’s take one more dive into the 2017 data to see what we can learn about developers who work remotely. …
