The nefarious Dr$.$ Evil has planted a slew of $$binary bombs$$ on our class machines. A binary bomb is a program that consists of a sequence of phases. Each phase expects you to type a particular string on stdin. If you type the correct string, then the phase is defused and the bomb proceeds to the next phase. Otherwise, the bomb explodes by printing "BOOM!!!" and then terminating. The bomb is defused when every phase has been defused.

End of assembler dump.

The function uses sscanf to read two integers from input.

It checks if at least one integer was successfully scanned. If not, it explodes the bomb.

If at least one integer is scanned, it compares the second integer with $7.$ If it's greater than $7,$ it explodes the bomb.

Otherwise, it uses a jump table to determine the next action based on the value of the second integer.

There are several jump targets based on the second integer's value.

After executing the corresponding action, it compares the first integer with a specific value. If it matches, the bomb is defused; otherwise, it explodes.

initially $,$ i read the code and thought the output would be $3$ X with X being any integer $0-7.$ Yet I tried all these outputs and the bomb still explodes. Can anyone please help??
