C# program to check if there are K consecutive 1’s in a binary number

CsharpServer Side ProgrammingProgramming

To check for consecutive 1’s in a binary number, you need to check for 0 and 1.

Firstly, set a bool array for 0s and 1s i.e. false and true −

bool []myArr = {false, true, false, false, false, true, true, true};

For 0, set the count to 0 −

if (myArr[i] == false)
   count = 0;

For 1, increment the count and set the result. The Max() method returns the larger of two number −

count++;
res = Math.Max(res, count);

Example

The following is the example to check if there are K consecutive 1’s in a binary number −

Live Demo

using System;
class MyApplication {
   static int count(bool []myArr, int num) {
      int myCount = 0, res = 0;
      for (int i = 0; i < num; i++) {
         if (myArr[i] == false)
            myCount = 0;
         else {
            myCount++;
            res = Math.Max(res, myCount);
         }
      }
      return res;
   }
   public static void Main() {
      bool []myArr = {false, true, false, false, false, true, true, true};
      int num = myArr.Length;
      Console.Write("Consecutive 1's = "+count(myArr, num));
   }
}

Output

Consecutive 1's = 3
