problem

 solution1:

class Solution {public:    vector
     
       constructRectangle(int area) {        int r = sqrt(area);        while(area % r != 0) r--;        return {area/r, r};    }};
     

 

solution2:

class Solution {public:    vector
     
       constructRectangle(int area) {        int r = 1;        for(int i=1; i*i <=area; i++)        {            if(area % i == 0) r = i;        }        return {area/r, r};    }};
