Food distribution issues

This morning on a day's class, Chinese back last night a study sister to solve the problem, should not be called to solve, called a point of thinking, because do not know why the program has been repeated output, the afternoon 7, 8 lessons went on the assembly experiment, feeling is and digital circuit circuit nothing to go (and hardware) , in the evening, took 1.5 hours to solve the problem.

The problem is as follows:

　　　　　　　　A pile of food, the first one to take one, take the remaining One-nineth, the second to take two, and then take the remaining One-nineth
So repeat until the last one takes the rest.

The code is as follows:

　　　　　　　　

1 usingSystem;2 usingSystem.Collections.Generic;3 usingSystem.Linq;4 usingSystem.Text;5 usingSystem.Threading.Tasks;6 //a pile of food, the first one to take one, take the remaining One-nineth, the second to take two, and then take the remaining One-nineth7 //so repeat until the last one takes the rest. 8 namespaceSub-food9 {Ten     class Program One     { A         Static voidMain (string[] args) -         { -  the             //int f=10, p;//F for Food quantity, p for number of people -             //While (true) -             //{ -             //int m = f;//temporary storage of food +             //While (true) -             //    { +             //p = 1;//every time you start with the first person , A  at             //Loop: -             //if (f-p)% 9 = = 0)//If this heap of food minus p can be divisible by 9, it means that the person in the back can continue to take it . -             //        { -             //if (f-p = = 0)//Judging if the rest of the food is equal to P. -             //            { -             //Console.WriteLine ("Number: {0}, food: {1}", p, m);// in             //Console.readkey (); -             //return; to             //            } +             //f = P-F-(F-P)/9;//The amount of food left after taking the food -             //p++; the             //Goto Loop; *             //        } $             //f = m;//Restore the quantity of the original foodPanax Notoginseng             //Break ;//exit number Cycle -             //    } the             //f++;//food increases by 1; +             //} A  the  +             //int F, p; -             ////bool B = true; $             ////while (b) $             ////{ -             //For (f = ten;; ++f) -             //{ the             //int temp = f; -             //p = 1;Wuyi  the  -  Wu             //Loop: -             //if (f-p)% 9 = = 0) About             //        { $             //if (f-p = = 0) -             //            { -             //Console.WriteLine ("Number: {0}, food: {1}", p, temp); -             //Console.readkey (); A             //return; +             //             } the             //f = P-F-(F-P)/9; -             //p++; $             //Goto Loop; the             //        } the             //f = temp; the  the             for(intf=Ten; ; f++) -             { inStep (F,1); the             } the             About             //    //} the             //} the  the  +         } -          Public Static voidStepintFintp) the         {Bayi             the  the             if(f-P)%9==0) -             { -                 if(F-P =0) the                 { the                      for(inti = P-1; i >0; i--) the                     { thef = f *9/8+i; -                     } theConsole.WriteLine ("food: {0}, number of people: {1}", F, p); the Console.readkey (); the                     return;94                 } thef = P-F-(F-P)/9; thep++; the step (F, p);98             } About             return;  -            101             102            103             104         } the     }106}

I first use recursion, due to the occurrence of the repeated output of the situation, and later with a for loop, I do not know how to get a code can not access the problem, the last use of the while loop. Although this problem is not difficult, but it took me some time to complete the task, finally I have three ways to achieve .
