Why WA on 5 test?
the code here:
        int type = in.nextInt();
        int size = in.nextInt();
        int n = in.nextInt();
        int count = 0;
        for (int i = 0; i < n; i++) {
            int curType = in.nextInt();
            int curSize = in.nextInt();

            if (type == 1) {
                if (curType == 1 && curSize <= size
                        || curType != 1 && curSize <= 2 * size) {
                    count++;
                }
            }
            if (type == 2) {
                if (curType == 1 && 2 * curSize <= size* Math.sqrt(2)
                        || curType != 1&&curSize <= size * Math.sqrt(2)) {
                    count++;
                }
            }
            if (type == 3) {
                if (curType == 1 && 2 * curSize <= size || curType != 1&&curSize <= size) {
                    count++;
                }
            }
        }
        out.print(count);
