Plus Minus

  • kingrayhan + 4 comments

    Javascript solution :)

    function plusMinus(arr) {
    let pos = 0, neg = 0 , zero = 0 , length = arr.length
    arr.forEach( n => {
        if( n > 0 )
            pos++
        else if( n < 0 )
            neg++
        else
            zero++
    } )
    console.log( (pos / length).toFixed(6) )
    console.log( (neg / length).toFixed(6) )
    console.log( (zero / length).toFixed(6) )
}

      lmao I did the same thing with same variables lol, with some differences. 

      function plusMinus(arr) {
    let pos = 0;
    let neg = 0;
    let zero = 0;
    arr.forEach(e => {
        if (e > 0)
            pos++;
        else if (e < 0)
            neg++;
        else if (e == 0)
            zero++;
    });
    console.log(pos / arr.length);
    console.log(neg / arr.length);
    console.log(zero / arr.length);
}

      Why it doesn't works with For loop? Thanks!

        It should work with for loop, you are probably doing something wrong. Post your code and I'll help you
