How do I compress a binary string?

1 Answer

1. Cut the string into short pieces of 8 characters each (1 byte = 8 bits)
2. Use Integer.parseInt(piece, 2); to convert the binary piece into an int.
3. Now cast the integer to a char.
4. Repeat this for every piece of the binary string.

What happens to values above 255 in binary?

An example of an 8-bit overflow occurs in the binary sum 11111111 + 1 (denary: 255 + 1). The total is a number bigger than 8 digits, and when this happens the CPU drops the overflow digit because the computer cannot store it anywhere, and the computer thinks 255 + 1 = 0. Many PCs have a 64-bit CPU.

Can you compress binary?

The more helpful answer is longer: what are the properties of the data being compressed? (sound, image, video, binary executable, etc.) Truly random data that is perfectly spread cannot be compressed. Compression relies on redundancy, and redundancy is very possible in random data.

How do you compress a string in Python?

Program to perform string compression in Python

1. res := blank string.
2. cnt := 1.
3. for i in range 1 to size of s – 1, do. if s[i – 1] is same as s[i], then. cnt := cnt + 1. otherwise, res := res concatenate s[i – 1] if cnt > 1, then.
4. res := res + last character of s.
5. if cnt > 1, then. res := res concatenate cnt.
6. return res.
