If you need to run it for the row, you should modify it appropriately. var words = []; var uniqueWords = []; $(“td”).each(function(){ words.push($(this).text()) }); $(words).each(function(){ for(var i = 0; i < uniqueWords.length; i++){ var current = uniqueWords[i]; if(current.word.toString() == … Read more
foo: &Foo is a reference to a Foo, while foo: Foo is a Foo value. The first signature declares that the function only borrows foo by taking a reference, the second signature declares that it takes ownership of the value. Although both compile, and both are correct, there is a difference in how you call … Read more

String) That means only index 0 is valid stringArray[0] and you get an out-of-range error for stringArray[1] stringArray[2] etc. Note: The question is not particularly related to Swift 4. All versions of Swift exhibit this behavior. 0 solved … Read more

I do not judge your algorithm or C conventions, friends who comment on your problem are totally right. But if you still do it in this way you can use this approach. #include <stdio.h> #include <string.h> void removeFirstAndLastChar(char* string) { memmove(string,string+1,strlen(string)); string[strlen(string)-1]=0; } int main(void) { char title[] = “ABC”; removeFirstAndLastChar(title); printf(“%s”, title); // Expected … Read more
