A computer engineer is designing a microprocessor based on quaternary $($base

$=4)$ bits. It uses thirty quaternary bits to represent a floating point value with

one bit for mantissa sign, $6$ bits for the exponent, and the remaining $23$ bits

for mantissa. The magnitude of its overflow limit in decimal system will

approximately be

$1232$

$1234$

$1235$

$1233$
