Problem

Convert an IP address in string format to a 4-byte integer.

Example

"192.168.1.101"   => 3232235877
"255.255.255.255" => 4294967295
"300.168.1.101"   => 0 (invalid)

Complexity

  • Time: O(N)
  • Space: O(1)

Instructions

  1. Complete the required APIs in question.c to attempt this question.
  2. Please don't edit the function prototype provided in question.c, your . solution might not compile if you do.
  3. If you need hints to solve the problem, look at hints.c instead.
  4. When you're done, compile your changes by running: make all
  5. Test your code using: ./question < input.txt or ./hints < input.txt.
  6. The solution is available in answer.c (compile using: make answer)
  7. Get the expected output using: ./answer < input.txt
  8. Feel free to include any additional header files or define additional functions.
