  #include <iostream>
  using namespace std;

  int main() {
  ios::sync_with_stdio(false);
  cin.tie(nullptr);
  unsigned int n;
  int q;
  cin >> n >> q;
  long long total = 0;
  while (q--) {
  int k;
  cin >> k;
  int bit_pos = k - 1;
  unsigned int mask = 1U << bit_pos;
  if ((n & mask) == 0) {
  unsigned int x = mask - (n & (mask - 1));
  total += x;
  n += x;
  }
  }
  cout << total << endl;
  return 0;
  }
