Arduino 7-Segment, more optimized

const char nums[10] = {0x7E,0x48,0xBC,0xB6,0xD2,0xE6,0xEE,0x72,0xFE,0xF6};
void setup() {
  for(int i=2;i<10;i++){
    pinMode(i, OUTPUT);
    digitalWrite(i, LOW);
  }
}
void dispnum7segment(int n) {
  for(int i=0;i<8;i+=1){
    digitalWrite(9-i,bitRead(nums[n],i));
  }
}
void loop() {
  for(int k=0;k<10;k++){
    dispnum7segment(k);
    delay(1000);
  }
