真尼玛难，回归简单题目：

function check(position, distance, m){        let count =1;        let i = 0;        let j = 1;        while(j < len){            if(position[j] - position[i] >= distance){                i = j;                count++;                if(count >= m){                    return true;                }            }            j++;        }        return false;    }    let len = position.length;    position.sort((a, b) => a - b);    // position.sort(function (a, b){return (a - b)});    let left = 1;    let right = (position[len - 1] - position[0]) / (m - 1);    let ras = 0;    while(left <= right){        let mid = Math.floor(left + (right - left)/2);        if(check(position, mid, m)){            res = mid;            left = mid + 1;        }else{            right = mid - 1;        }    }    return res;
