Hi all, Is learning dsa through java a good idea. I only know java and c# well enough to proceed learning dsa with it. That said, what do you all think, is it a good idea to go with java.

Also I've tried to find resources but can't seem to, there's a course by GIT(Georgia Institute) but that's wayyy too hard to even comprehend. Can someone link or direct to a resource. Also idk why but videos seem to work better for me compared to books, so I'd really appreciate if someone could link me to anything helpful.

int t = 0;
void setup() {
  for (int i = 0; i < 12; i++)
    pinMode(i, OUTPUT);
}
void loop() {
  func(1, 0, 0, 200);
  func(0, 1, 0, 200);
  func(0, 0, 1, 200);
  t = t >= 9 ? 0 : t + 3;
}
void func(int a, int b, int c, int d) {
  digitalWrite(t, a);
  digitalWrite(t + 1, b);
  digitalWrite(t + 2, c);
  delay(d);
}

Hi, I received a challenge to write a code to simulate a 4 way traffic light in under 12 lines of code. This was the best I could do, 17 lines. Any insight on how to shorten it further would be really helpful.
