comment Number of way to move form $(1,1)$ to $(n,n)$ in a square grid taking exactly $k$ turns
There will be $(k+1)/2$ vertical and $k/2 + 1$ horizontal segments. Can you please elaborate more?

no k=1 is also valid for example RRRR...R(n times)DDDD....D(n times) that is you are only turning once at top right corner.

@user92774 moves available are right and down. I am naming the top left corner as (1,1) and bottom right corner as (n,n).

comment Mod question: $2^{-1} \bmod 5 = 3$
$\mathbb{Z}_p - \{ 0 \}$ is a group, so every element has an inverse. So to find 2's inverse find $x$ such that $2x \equiv 1 \pmod 5$.
