Output

One acceptable solution was -------------------------------------------------- void stepper(int xw){int s=0,i,j;int a[]={1,3,2,6,4,12,8,9};for(i=0;i<xw;i++,s=(s+1)&7)for(j=0;j<4;j++)digitalWrite(j+1,(a[s]>>(3-j))&1);} -------------------------------------------------- Explanation: • We combine the eight cases into an array a using the 4‐bit pattern (bit3 for pin1 … bit0 for pin4). • In each loop iteration we run a small inner loop over j=0…3 and output the corresponding bit by shifting. • Instead of s=(s+1)%8, we use s=(s+1)&7, which works because 8 is a power of 2. This solution is less than 300 bytes (ignoring whitespace) and meets the requirements.

Output

One acceptable answer was to pre‐encode the eight 4‐bit step patterns in an array, then for each step shift out the bits to digitalWrite. For example, this solution (under 300 non‐whitespace bytes) is valid: ------------------------------------------------- void stepper(int n){ static char s[]={1,3,2,6,4,12,8,9}; for(int i=0;n--;i=(i+1)%8){ int v=s[i]; digitalWrite(1,v>>3&1); digitalWrite(2,v>>2&1); digitalWrite(3,v>>1&1); digitalWrite(4,v&1); } } ------------------------------------------------- How it works:  • The array s holds bit‐patterns for pins 1–4 (with bit0 corresponding to digitalWrite(4,…) and bit3 to digitalWrite(1,…)).  • The loop runs n times (n is the input number of steps) and cycles through s.  • Each digitalWrite gets its value by shifting the stored value and masking with 1. Any solution under 300 bytes (ignoring whitespace) is acceptable.
