C# program to find the length of the Longest Consecutive 1’s in Binary Representation of a given integer

To fetch the consecutive 1’s, use the Bitwise Left Shift Operator. Here is our decimal number.

i = (i & (i << 1));

Loop the above until the value of I is 0 and fetch the length using a variable; count here.

while (i != 0) {
   i = (i & (i << 1));
   count++;
}

The example we have taken here is 150.

The binary for 150 is 10010110. Therefore, we have two consecutive one’s.

Example

 Live Demo

using System;
class Demo {
   private static int findConsecutive(int i) {
      int count = 0;
      while (i != 0) {
         i = (i & (i < 1));
         count++;
      }
      return count;
   }

   // Driver code
   public static void Main() {
      // Binary or 150 is 10010110
      Console.WriteLine(findConsecutive(150));
   }
}
