Decrypt the ciphertext which is encrypted with the ElGamal cipher. The parameters are: p$=31847$p$=31847,\backslash$beta $=5\backslash$beta $=5,$and $\backslash$alpha $=18074\backslash$alpha $=18074.$The decryption procedure is as follows:s

$$ Calculate the private key from the above values by solving the discrete logarithm;

$$ Am only interested in getting the a value $($knowing how to do the discrete logerith part$($and a should be $7899)$
