# Array Properties And Methods Challenge

Can someone please help me with this challenge. Test case 4 and 5 work but 1,2 and 3 do not. The player receives points after passing each level of a game. The program given takes the number of passed levels as input, followed by the points gained for each level, and creates the corresponding array of points. Complete the program to calculate and output to the console the sum of all gained points. Sample Input 3 1 4 8 Sample Output 13 function main() { //take the number of passed levels var levels = parseInt(readLine(),10); var points = new Array(); var count = 0; while(count<levels){ var elem = parseInt(readLine(),10); points[count] = elem; count++; } var sum = 0 + points.length + elem + count; //calculate the sum of points //output console.log(sum); }

Hi This is my programming and it worked very well function main() { //take the number of passed levels var levels = parseInt(readLine(),10); var points = new Array(); var count = 0; while(count<levels){ var elem = parseInt(readLine(),10); points[count] = elem; count++; } var sum = points[0]; //calculate the sum of points for (i=1;i< points.length ;i++){ sum = sum + points[i]; } //output console.log(sum); }

Update on the problem. I managed to get all test cases to work, thank you to everyone who commented... here is the solution. function main() { //take the number of passed levels var levels = parseInt(readLine(),10); var points = new Array(); var count = 0; while(count<levels){ var elem = parseInt(readLine(),10); points[count] = elem; count++; } var sum = points.reduce(function(a, b) { return a + b; }, 0); //calculate the sum of points //output console.log(sum); }

This worked for me function main() { //take the number of passed levels var levels = parseInt(readLine(),10); var points = new Array(); var count = 0; while(count<levels){ var elem = parseInt(readLine(),10); points[count] = elem; count++; } var sum = 0; //calculate the sum of points for(i = 0; i < points.length; i++){ sum = sum + points[i]; } console.log(sum); }

What does .reduce mean? We haven't had a lesson on that, yet it is used in the sample solution.

var sum = points[0]; //calculate the sum of points for(i=1; i<points.length; i++){ sum += points[i]; } //output console.log(sum);

Here is the correct code function main() { //take the number of passed levels var levels = parseInt(readLine(),10); var points = new Array(); var count = 0; while(count<levels){ var elem = parseInt(readLine(),10); points[count] = elem; count++; } var sum = points.reduce(function(a, b) { return a + b; }, 0); //output console.log(sum); }

Gordon, readLine is the input that will be used to test your code. So how would I do that if the numbers are changing for each case?

The answer is. please copy the whole code and paste it function main() { //take the number of passed levels var levels = parseInt(readLine(),10); var points = new Array(); var count = 0; while(count<levels){ var elem = parseInt(readLine(),10); points[count] = elem; count++; } var sum = points[0]; //calculate the sum of points for (i=1;i< points.length ;i++){ sum = sum + points[i]; } //output console.log(sum); }
