Active and Inactive cells after k Days

Given a binary array of size n where n > 3. A true (or 1) value in the array means active and false (or 0) means inactive. Given a number k, the task is to find count of active and inactive cells after k days. After every day, status of i’th cell becomes inactive if its left and right cells have same value, i.e., either both are 0 or both are 1.
Since there are no cells before leftmost and after rightmost cells, the value cells before leftmost and after rightmost cells is always considered as 0 (or inactive).
