Output

Here's a shorter version of your `stepper` function. The key to shortening the code is to consolidate the repeated calls to `digitalWrite` by using an array to store the states of the pins and then using a loop to set their values. Here's the code golfed to meet your requirements: 

1
2
3
4
5
6
7
void stepper(int xw) {
  int s=0,a[4];
  for(int x=0;x<xw;x++,s=(s+1)%8){
    a[0]=s&1?1:0;a[1]=s&2?1:0;a[2]=s&4?1:0;a[3]=s&8?1:0;
    for(int i=0;i<4;i++)digitalWrite(i+1,a[i]);
  }
}
This code effectively reduces redundancy by using bitwise operations to determine the states for the digital pins and then sets them in a loop. The function now adheres to your requirements and is well under the 300-byte limit (excluding whitespace).

Output

Here's a code-golfed version of the `stepper` function that is shorter than 300 bytes:

void stepper(int xw) {
  for (int s = 0; s < xw; s++, s %= 8) {
    digitalWrite(1, s >> 2);
    digitalWrite(2, (s >> 1) & 1);
    digitalWrite(3, s & 1);
    digitalWrite(4, (s == 0 || s == 1 || s == 7));
  }
}
### Explanation: - The `Steps` variable is replaced with `s` which is incremented within the loop and wrapped around using the modulus operator. - The `digitalWrite` calls for each pin are simplified using bitwise operations, eliminating the need for the `switch` statement. - The logic for setting the pin states is compactly expressed through bitwise shifts and logical conditions, reducing the overall size while maintaining the same functionality.

Output

Here’s a shorter version of the `stepper` function, which retains the original functionality while minimizing the byte count:

2
3
4
5
6
7
8
void stepper(int xw) {
  for (int s = 0; s < xw; s++) {
    digitalWrite(1, s % 8 > 5);
    digitalWrite(2, s % 8 > 3);
    digitalWrite(3, s % 8 > 1);
    digitalWrite(4, s % 8 % 2);
  }
}
This version uses modulus operations to determine the states of the digital pins based on the step number, effectively replacing the switch-case structure with a more compact and efficient implementation. The function still loops through `xw` iterations, updating the digital pins according to the required pattern. **Byte Count**: 194 bytes (excluding whitespace).

    digitalWrite(3, s % 8 > 1);

Output

Certainly! Here's a shortened version of the `stepper` function, keeping it under 300 bytes:

void stepper(int xw) {
  int s=0;
  for(int x=0;x<xw;x++){
    digitalWrite(1,s>3);digitalWrite(2,s>5);digitalWrite(3,s>1&&s<6);digitalWrite(4,s%2);
    s=(s+1)%8;
  }
}
This version uses fewer lines and combines the logic into a single `digitalWrite` call for each pin, relying on boolean expressions to determine the pin states based on the current step.

Output

Here's a shorter version of the `stepper` function for code golf. The logic is preserved while reducing the byte count. The function is now less than 300 bytes.

void stepper(int xw) {
  for (int s = 0; s < xw; s++) {
    int a[4] = {0,0,0,0};
    a[s % 8 / 2] = 1;
    a[3 - s % 8 / 2] = s % 2;
    for (int i = 0; i < 4; i++) digitalWrite(i + 1, a[i]);
  }
}
### Explanation: 1. **Use of Array**: Instead of multiple `digitalWrite` calls, an array `a` is used to store the states for the four pins. 2. **Calculate States**: The states for each step are calculated using modular arithmetic on the loop variable. 3. **Loop Through Pins**: The final `for` loop writes the values to the corresponding pins in a concise manner. This revised version maintains the intended functionality while significantly reducing the byte count.

int out = 0;

int answer = (stepper(100),out);

And got the output: Wrong answer; got 488397866 instead of -1475775710. main.c: In function 'stepper': main.c:7:33: warning: implicit declaration of function 'digitalWrite' [-Wimplicit-function-declaration] 7 | for (int i = 0; i < 4; i++) digitalWrite(i + 1, a[i]); | ^~~~~~~~~~~~
