Apply the logic to compress the data.
Fristly we take c and byt variable and ex-or by c^c then it become zero.
Then we apply a for loop and give a condtion if *(key+i) != 0. then condition true if it not then falls.
After this we shift the c left four bit and save the data inside the byt and again read the next bit and aplly same logic now it consider a next bit inside the last four bit in c and or with the byt and save two bit data.
