General discussions: How to iterate by lines vertical in js? Like in the Triangle task

Stas Yasinskiy 2022-10-20 10:34:45

let tringle = input().split();   
for(i=0; i<tringle.length; i++) {
    output(tringle[i]);
}

input = 578 293 628
698 1079 1182
987 1606 3744
981 1559 632
...

Hello,

What exactly do you mean by "iterate by lines vertical"?
Where did you get this input data? The input data provided for the Triangle task is in a different format.

Task #9 When I iterate over input data by for loop this method gives only the first triple digits.

I still don't understand what you mean. What output are you getting? If you submit your answer + code (not copying to forum), I will be able to see the code, even if the answer is wrong.

If you're trying to process the data given by Problem #9, read on.

The first line of data should tell you how many iterations to loop for. What I would do is read in the first line as n, then loop (i=0; i<n; i++){ ... }. You will need to call input() inside of your loop body to read each subsequent line.

let triangle = input().split(' ');
let S = 0;
for(i=0; i<triangle.length; i++) {
    S += + tringle[i] / 2;
}
let sum = S * ( S - triangle[0]) * ( S - triangle[1]) * ( S - triangle[2]);
    if(sum <= 0) {
        sum = 0;
    } else {
    sum = 1;
}
output(sum);

Stas, Hi!

Every input() allows you to assign next line of input into the variable.

So your input() should be inside the loop (but you have it outside).

E.g.

let numLines = input() * 1;  // I use *1 to make number from string, I'm poor at javascript

for (let i = 0; i < numLines; i++) {
    let nextTriangle = input().split(' ');
    // ... do something
}

Thank you guys for your help something becomes clearer
