**Explanation:** * **Loop:** The outer loop (`for (int i = 0; i < xw; ++i)`) remains the same, iterating `xw` times. * **Pattern Recognition:** The original `switch` statement implements a repeating pattern for the `digitalWrite` values. We can represent this pattern using modulo (`%`) and comparison operators. * **Pin 1:** Pin 1 is HIGH (`1`) when `i % 8` is greater than 4. * **Pin 2:** Pin 2 is HIGH when `i % 8` is greater than 2 and less than 6. * **Pin 3:** Pin 3 is HIGH when `i % 4` is greater than 1 and less than 4. * **Pin 4:** Pin 4 alternates every step (`i % 2`). **Byte Count:** The new code is well under the 300-byte limit.

This version takes advantage of the cyclical nature of the steps and uses modulo arithmetic to determine the state of each pin based on the current step. It eliminates the switch statement and significantly reduces the code size.

Here's how it works and how I golfed it: * **Combined Loops:** The original code had nested loops. I combined the `x` loop for iterations and the `Steps` logic into a single `for` loop. * **Pattern Recognition:** Instead of a `switch` statement, I noticed the patterns in the `digitalWrite` calls for each pin based on the step value (`s`). * **Conditional Expressions:** I used compact conditional expressions (ternary operator) to directly set the pin values within the `digitalWrite` calls. This version is significantly shorter and avoids the verbose `switch` statement.

Here's how it works: 1. **Loop:** The outer loop `for(int i=0;i<xw;++i)` iterates `xw` times, just like the original code. 2. **Pattern Recognition:** Instead of a `switch` statement, we directly calculate the pin states based on the loop index `i`. Notice the repeating pattern of `1`s and `0`s for each pin across the eight steps. 3. **Modulo Operator:** The `% 8` (modulo 8) ensures the pattern repeats every eight steps. 4. **Bitwise AND (`&`) and Greater/Less Than Comparisons:** These are used to isolate specific ranges within the eight-step cycle where a pin should be HIGH (1). Let me know if you'd like a more detailed explanation of any particular part!

int out = 0;
int digitalWrite(int pin, int value) {
  out *= 101;
  out += pin;

int main() {


int answer = (stepper(100),out);
int expected = -1475775710;
if (answer != expected) {
    printf("Wrong answer; got %d instead of %d.\n", answer, expected);
    exit(1);
}
printf("All tests passed\n");
}
And got the output: Wrong answer; got 615377977 instead of -1475775710. main.c: In function 'stepper': main.c:4:5: warning: implicit declaration of function 'digitalWrite' [-Wimplicit-function-declaration] 4 | digitalWrite(1,i%8>4); | ^~~~~~~~~~~~
