86. Circular Buffer Read

#include <stdio.h>

typedef struct {
    int buffer[10];
    int head;
    int tail;
    int count;
    int capacity;
} CircularBuffer;
int printed=0;
void read_bytes(CircularBuffer *cb, int n) {
    // Your logic here
    while(cb->count){
        n--;
        if(n==0){
        printf("%d",cb->buffer[cb->tail]); 
        cb->tail = (cb->tail + 1) % cb->capacity;
        cb->count--;
        break;
        }
        else
        printf("%d ",cb->buffer[cb->tail]);
        cb->tail = (cb->tail + 1) % cb->capacity;
        cb->count--;
        
    }
    for(int i=0; i<n; i++){
        if(i!=0) printf(" ");
        printf("NULL");
    }
    printf("\n");
    printf("Tail: %d",cb->tail);
}

int main() {
    CircularBuffer cb = {
        .buffer = {10, 20, 30, 40, 50, 60, 70, 80, 90, 100},
        .head = 3,
        .tail = 7,
        .count = 6,
        .capacity = 10
    };

    int n;
    scanf("%d", &n);
    read_bytes(&cb, n);

    return 0;
}

logic is actually simple had to complicate it to match the formatting pf the cases
