In a double hashing scheme, $h1(k) = k \pmod{11}$ and $h2(k) = 1 + (k \pmod 7)$ are the auxiliary hash functions. The size $m$ of the hash table is $11$. The hash function for the $i$-th probe in the open address table is $h1(k) + i \cdot h2(k) \pmod m$. The following keys are inserted in the given order: $63, 50, 25, 79, 67, 24$. The slot at which key $24$ gets stored is \\\\\\\. (Answer in integer)
