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
const n = arr.length; console.log(arr.filter((v,i) => v>0).length/n); console.log(arr.filter((v,i) => v<0).length/n); console.log(arr.filter((v,i) => v==0).length/n);
