#Day6- Occurrence of Two one in a vector

Task: Find the Occurrence of two one in a given vector.

Find the number of times  [1,1] pattern occur in the  given vector

Note: This code can be done using the in-built command. But for the challenge, I am trying to avoid those

x=[1,1,1,1,3,5,6,7,12,3,4,5]

y=3

x1=[1,2,1,3,4,5,1]

y=0


Matlab Code:

         

function y = lengthOnes(x)

  n=length(x);

  y=0;

  for i=2:1:n

      if x(i)==1 && x(i-1)==1

          y=y+1;

      end

     

  end         

     

end

Sample Input and Output

>> y = lengthOnes(x)

y =

     3

>> x1=[1,2,1,2,3,4,5,1];

>> y = lengthOnes(x1)

y =

     0

>> y = lengthOnes(x2)

y =

     7
