Soooo... I have this pattern... 110011001100...

in Programming Questions • 2 years ago

I have this pattern:

11001100110011001100…

I’d like to write a function which returns 1 or 0 based on the position in this list. That is, an input of 0 returns 1. An input of 1 returns 1. An input of 2 returns 0. An input of 3 returns 0, etc.

Can anyone provide a clever way to code this?

Thanks!

A little modulomagic helps:

void setup() {
size(500, 500);
}
void draw() {
int x= calc(frameCount);
println(x);
}
int calc(int input) {
int output;
if (input%4 ==0 || input%4 ==1) {
output=1;
}
else {
output=0;
}
return output;
}

Hope that helps.

try some charAt() - " Returns the character at the specified index."

/*
returns 1 or 0 based on the position in a list.
input of 0 returns 1.
input of 1 returns 1.
input of 2 returns 0.
input of 3 returns 0, etc.
*/
String yourList = "11001100110011001100";
void setup(){
println ( "input of 0 returns " + calc(0) );
println ( "input of 1 returns " + calc(1) );
println ( "input of 2 returns " + calc(2) );
println ( "input of 3 returns " + calc(3) );
}
// is it a one or zero
int calc(int input) {
return int(yourList.charAt(input)==49); //49 is the character for 1
}

You can also use substring() instead of charAt
