思路：
每次取模换率，把多出来的加到膜完的数上面。

class Solution 
public:
    int numWaterBottles(int numBottles, int numExchange) 
        int res=numBottles;
        while(numBottles>=numExchange)
        
            int tt=numBottles/numExchange;
            res+=tt;
            numBottles%=numExchange;
            numBottles+=tt;
        
        return res;
    
;
