    TypeScript Solution

    function plusMinus(arr: number[]): void {

    let zeros = 0
    let negatives = 0 
    let positives = 0 
    
    for (const i in arr ){
        if (arr[i] > 0 && arr[i] <=100) positives++;
        if (arr[i] === 0) zeros++;
        if (arr[i] < 0 && arr[i] >= -100) negatives++;
    }
    const z = zeros / arr.length
    const n = negatives / arr.length
    const p = positives / arr.length
    
    console.log(p.toFixed(6))
    console.log(n.toFixed(6))
    console.log(z.toFixed(6))
}
