## 改良版
- t從area的平方根開始跑迴圈
- leetcode submit runtime 58%, memory 76%

var constructRectangle = function(area) {
    let W=1,L=area;
    for(let t = Math.floor(Math.sqrt(area)); t>1; t--){
        if(area%t==0){
            W = t;
            L = area/t;
            break;
        }
    }
    return [L,W];
};

## 初見
- 土法煉鋼跑迴圈求L和W, t=2開始直到t>area的平方根為止
- leetcode submit runtime 58%, memory 15%

var constructRectangle = function(area) {
    let L=area,W=1;
    let tArea = area;
    for(let t=2; t<=Math.sqrt(area); t++){
        if(area%t==0){
            W = t;
            L = area/t;
        }
    }
    return [L,W];
};
