]]> Given an array of ones and zeroes, convert the equivalent binary value to an integer.

Eg: [0, 0, 0, 1] is treated as 0001 which is the binary representation of 1.

Examples:

Testing: [0, 0, 0, 1] ==> 1
Testing: [0, 0, 1, 0] ==> 2
Testing: [0, 1, 0, 1] ==> 5
Testing: [1, 0, 0, 1] ==> 9
Testing: [0, 0, 1, 0] ==> 2
Testing: [0, 1, 1, 0] ==> 6
Testing: [1, 1, 1, 1] ==> 15
Testing: [1, 0, 1, 1] ==> 11

The link problem is here.

Solution:

#include <stddef.h>

unsigned binary_array_to_numbers(const unsigned *bits, size_t count)
{
  unsigned numbers=0;
  
  for(size_t i = 0; i < count; i++)
  {
    numbers += (bits[i] * pow(2,count-i-1));
  }
  return numbers;
}
