排班系统 c语言解法
学校实验楼有7名保安人员:钱、赵、孙、李、周、吴、陈。由于工作需要进行轮休制度,一星期中每人休息一天。预先让每一个人选择自己认为合适的休息日。请编制程序,打印轮休的所有可能方案。当然使每个人都满意,例如每人选择的休息日如下:
钱:星期一、星期六
赵:星期二、星期四
孙:星期三、星期日
李:星期五
周:星期一、星期四、星期六
吴:星期二、星期五
陈:星期三、星期六、星期日

哦哦~第一直觉是用递归遍历所有可能解法~这是排列组合的变种~

最近到底怎么啦~虽然认真起上来会解~但九九懒敲代码了~

把人数改成70就笑了~~
不过九九也认为这是一个好程序~~

//递归大概是这样吧
void Travel(int n, int* a)
{
    for(int i = 0; i < 7; i++)
    {
        a[n] = i;
        Travel(int n, int* a);
        if(n == 0)
        {
               //判断条件
        }

思路应该没有问题~就是感觉要用二维数组~

手头没C环境 图省事儿用JS写个,至少很容易看明白思路:
程序代码:
clear();

var _eWeek = ['', '', '', '', '', '', ''];

function initData(){
    var peoples = [];
    peoples[0] = {cnFirstName:''};
    peoples[1] = {cnFirstName:''};
    peoples[2] = {cnFirstName:''};
    peoples[3] = {cnFirstName:''};
    peoples[4] = {cnFirstName:''};
    peoples[5] = {cnFirstName:''};
    peoples[6] = {cnFirstName:''};

    var wantsData = [];
    wantsData[0] = [];
    wantsData[0][0] = 1;
    wantsData[0][1] = 6;
    wantsData[1] = [];
    wantsData[1][0] = 2;
    wantsData[1][1] = 4;
    wantsData[2] = [];
    wantsData[2][0] = 3;
    wantsData[2][1] = 0;
    wantsData[3] = [];
    wantsData[3][0] = 5;
    wantsData[4] = [];
    wantsData[4][0] = 1;
    wantsData[4][1] = 4;
    wantsData[4][2] = 6;
    wantsData[5] = [];
    wantsData[5][0] = 2;
    wantsData[5][1] = 5;
    wantsData[6] = [];
    wantsData[6][0] = 3;
    wantsData[6][1] = 6;
    wantsData[6][2] = 0;
    return {wantsData:wantsData, peoples:peoples};
}

function getAllTrun(peoples, wantsData){
    var turn = [];
    var last = [];
    var bOver = false;
    var limit = 0;
    while (true){
        if (limit++ > 1000000){    // 可去掉
            break;
        }
        for (var t in wantsData){
            if (typeof wantsData[t] != 'object'){
                continue;
            }
            if (last[t] >= 0){
            }else{
                last[t] = 0;
            }
            for (var l=t; l>=0; l--){
                if (wantsData[l].length <= last[l]){
                    last[l] = 0;
                    if (l == 0){
                        bOver = true;
                        break;
                    }else{
                        last[l-1] ++;
                    }
                }    
            }
        }
        if (bOver){
            break;
        }
        var unit = [];
        var weekStat = [];    // 统计每天有几个人休息,如果限制当天不能全休息可以通过此数据判断
        for (var t in wantsData){
            if (typeof wantsData[t] != 'object'){
                continue;
            }
            var w = wantsData[t][last[t]];
            if (weekStat[_eWeek[w]] > 0)
                weekStat[_eWeek[w]] ++;
            else
                weekStat[_eWeek[w]] = 1;
            unit.push({week:w, people:t, stat:weekStat});
        }

        last[t] ++;
        turn.push(unit);
    }
    return turn;
}
var data = initData();
var all = getAllTrun(data.peoples, data.wantsData);

// test 
for (var a in all){
    var unit = [];
    for (var t in all[a]){
        unit.push("星期"+_eWeek[all[a][t].week]+":"+peoples[all[a][t].people].cnFirstName);
    }
    console.log(unit.join(","));
