Follow the other peer’s comments for future community interactions. Your problem is that you are not stopping the loop when you find the position: Node Delete(Node head, int position) { // Complete this method int pos = 0; Node current = head; Node previous = null; if(position == 0 && head.next == null){ return null; … Read more
You have the # lines as a separation between your matrix. So if you loop line by line on your file, you can separate the matrix with this # lines, and built them : file = open(“file.txt”, “r”) lines = file.readlines() At this point, lines is a list. lines[i] is the line n° i+1 as … Read more
Okay. Thanks to @AshishJohn this question is now solvable. In the provided link you can see a define in the beginning which changes the syntax of for loops: #define for(i,a,b) for(i=a;i<b; i++) So for(j,0,np) will be converted by the preprocessor to: for (j=0; j<np; j++) which is a normal for loop. np is also declared … Read more
Remove the first line of your function sumOfRange() var numbers = [1,-1,1,-1,1] because you are re-initializing the value of numbers, you need to use to array that is passed to the function when it is called. function sumOfRange(numbers) { var sum = 0; for (var i = 0; i < numbers.length; i++) { sum += … Read more
This query creates a column called COL and puts literal value of ‘ID’ in it. It then provides the first (or highest) ID (numeric or alphabetic depending on what type of field ID is) and places it in the same row as the literal value “ID” under the column named (MAX). It then takes the … Read more

It is equivalent to calling the PrintWriter(Writer out) with the following argument: new BufferedWriter(new OutputStreamWriter(out)) The BufferedWriter is injected for performance reasons. where is my data buffered? In the BufferedWriter. why doesnt “Hello World” get printed The “Hello World” text is … Read more
With your server code self hosted and a javascript client calling into your server methods, becoming your browser based client, your design should work. I am looking at this. https://learn.microsoft.com/en-us/aspnet/signalr/overview/deployment/tutorial-signalr-self-host But I think you’ll need to figure out scale out scenarios and server failure scenarios with the self host. In case there is a patch … Read more
NULL results in a false condition. You could imagine that NULL is a 0, so this: if(NULL) would be equivalent to this: if(0) thus your code would become: #include <stdio.h> #include <iostream> int main() { if(0) std::cout<<“hello”; else std::cout<<“world”; return 0; } where is obvious that because 0 results to false, the if condition is … Read more
You declare myElement, but it is just null. In your function, trying to set an index of a null variable will do nothing. Additionally, you should increment after using the value, otherwise you miss out on the 0th element. var myElement = []; var countElement = 0; function wikiParsed(langPrefixElement) { myElement[countElement++] = countElement; } wikiParsed(); … Read more
There’s nothing wrong with the alignment of the row. What are misaligned are the two tables inside the rows. Compare: <!–START OF EMAIL BODY –> <table cellpadding=”0″ cellspacing=”0″ border=”0″ width=”600″ align=”center”> <!– LOGO AND SOCIAL MEDIA –> <table cellpadding=”0″ cellspacing=”0″ border=”0″ width=”600″ bgcolor=”#FFFFFF”> One of them is centred. The other is left aligned. solved HTML … Read more
min1 = score_arr should be changed to min1 = score_arr[i]. min1 = score_arr is setting min1 to the whole list, so the next iteration fails on the line if score_arr[i] < min1 since score_arr[i] is a float and min1 is now a list (as indicated by the error message). But, a better way to find … Read more
You can use jQuery’s .attr() to achieve what you want: Comments in code for js, – and also in your html, start your rowspan off as 2 (or the number of rows you start in your table) and get rid of the colspan in the second row – the rowspan handles the missing column $(‘#addPeople’).click(function … Read more
