Cho một số nguyên X, nhiệm vụ là in chuỗi và tìm tổng của chuỗi
Ví dụ.
Đầu vào. X = 2, N = 5
Đầu ra. Tổng = 31
1 2 4 8 16
Đầu vào. X = 1, N = 10
Đầu ra. Tổng = 10
1 1 1 1 1 1 1 1 1 1
Khuyến khích. Vui lòng thử cách tiếp cận của bạn trên {IDE} trước, trước khi chuyển sang giải pháp
Cách tiếp cận. Ý tưởng là duyệt qua chuỗi và tính tổng N số hạng của chuỗi. Thuật ngữ thứ N của chuỗi có thể được tính là.
Số hạng thứ N = [N-1]Số hạng * X
Dưới đây là cách triển khai của phương pháp trên.
