Why is your codeforces rating?

Why not keep a left and right variable that gives the last updated index and decrement and increment further, do not check in-between values of left and right?

That doesn't work in all cases especially when the array is huge and many forbidden cases are there.

​​​@@KaranKumar-hw2bqCan you give any counter case? Yes, there maybe forbidden ones, we make a hashmap or something to check if the current index is possible or not, then I can check invalid >r(storing rightmost index), i.e. check each value of r +2n in a iterative way and update r accordingly. Similarly we can do for left.
