You have a stream of data represented by a series of nonnegative integers. The risk value of the data is determined by the number of adjacent indexes where the numbers have different parity $($i$.$e$.$ different remainders when divided by $2).$ Additionally, some data is Iost and indicated by $\text{'}O\text{'}$ values. You can replace the $\text{'}O\text{'}$ values with any positive integer.

You are also given an array called Arr, which represents the stream of data and is a size of $N.$

Calculate the minimum risk value achievable by substituting 'of's with positive integers.

Function description

Complete the function Parity$().$ This function takes the following $2$ parameters and returns the required answer:

$N$ : Represents the size of the stream of data

Arr. Represents the stream of data
