A pincode consists of N integers between 1 and 9. In a valid pincode, no integer is allowed to repeat consecutively. Ex: The sequence 1, 2,1, 3 is valid because even though 1 occurs twice, it is not consecutive. However, the sequence 1, 2, 2, 1 is invalid because 2 occurs twice, consecutively. Utilize a for loop and branch statements to write a function called pinCodeCheck to detect and eliminate all the consecutive repetitions in the row array pinCode. The function outputs should be two row arrays. The row array repPos contains the positions pinCode where the consecutive repeats occurs, and the row array pinCodeFix is a valid pincode with all the consecutive repeats removed in pinCode.

The function definition to this question can be defined as follows:

Function definition:%defining method

function [ rep_Pos, pincode_Fix ] = pincode_check( pincode )

      pincode_Fix_Temp = pincode; %defining variable that holds a value

      rep_Pos_Temp = []; %defining array

  for i = 1:length(pincode) %defining a loop to count value  

      if((i > 1)) & (pincode(i) == pincode(i - 1)) %checking value

          rep_Pos_Temp([i]) = i; %store value in rep_Pos_Temp array

      else

          rep_Pos_Temp([i]) = 0; %array assign as 0

      end

  end

  for i = 1:length(pincode) %loop to count value length

      if(rep_Pos_Temp(i) > 0)%check condition

          pincode_Fix_Temp(i) = 0; %assign value to 0

      end

  end

%removing all array value

  rep_Pos_Temp = nonzeros(rep_Pos_Temp); %assign value in rep_Pos_Temp  

  pincode_Fix_Temp = nonzeros(pincode_Fix_Temp); %assign value in pincode_Fix_Temp

  rep_Pos = rep_Pos_Temp; %re positing value  

  pincode_Fix = pincode_Fix_Temp'; % assign value in pincode_Fix  

end

Explanation:

In the given method definition a method a temporary variable "pincode_Fix_Temp" and an array "rep_Pos_Temp" is declared, which holds the values of the return arrays.

this would start to sound a little like mortal combat
