Conversion (any to any)

#1

Question is not clear to me

#2

in this question
first line of input contain sb (source number system base),
then next line is db (destination number system base)
sn (number in source format).

now you have to convert sn(given number) from source base to destination base
for example
8
2
33
here you have to convert 33 of octal(base 8) to binary (base 2 )
33 of octal is equal to 11011 in binary so this is ans

to solve this make function of all conversions and then call them accordingly
