Dichotomy Method C #

Two-part method

Example: Look at the price of goods

First show a product priced at 999 yuan, the participants to guess the price of the goods. In the process of guessing the price, the referee will give more participants the price, corresponding to the "high" or "low" hint.

Table 1-1 Two-way guess commodity price (640)

Number	Price range	Middle Value
1th time	0~999	500
2nd time	500~999	750
3rd time	500~750	620
4th time	620~750	680
5th time	620~680	650
6th time	620~650	630
7th time	630~650	640

//0~999 guess the priceConsole.WriteLine ("Please enter the price of the product:"); intCommoditprices =convert.toint16 (Console.ReadLine ()); Console.WriteLine ("participants:"); intprices=convert.toint16 (Console.ReadLine ()); intI=1;  while(true) {i++; if(prices<commoditprices) {Console.WriteLine ("it's low."); Console.WriteLine ("participants:"); Prices=convert.toint16 (Console.ReadLine ()); }               Else if(prices>commoditprices) {Console.WriteLine ("High."); Console.WriteLine ("participants:"); Prices=convert.toint16 (Console.ReadLine ()); }               Else{Console.WriteLine ("Congratulations, guess right, guess {0} times in total. ", i);  Break; }} console.readkey ();
