JS算法例子

1. 换酒瓶算法：初始有n瓶酒，m瓶空瓶子可换一瓶酒，求最多能喝几瓶酒

   //返回喝酒的瓶数，参数1初始酒数量，参数2空瓶数量换一瓶酒
   function changeBottle(initBottle,numchange){
       let total = 0;//喝的瓶数
       let empty = 0;//空瓶数
       while(initBottle>0){//只要有酒就继续喝
           total += initBottle;
           empty += initBottle;
           initBottle = 0;
           let changes = Math.floor(empty/numchange);
           if(changes>0){
               initBottle = changes;
               empty = empty % numchange;
           }
       }
       console.log(total);
   
   }
