Proof of Legendre's Conjecture

Legendre's conjecture states that there exists a prime between $n^2$ and $(n+1)^2$, for every positive integer $n$. Here I prove that for sufficiently large $n$, there is a prime number between $n^2$ and $(n+1)^2$. The proof relies on the idea of counting the maximum power, $o_p(n)$ of a prime $p\leq n$ such that $p^{o_p(n)}||n$.
