Đưa ra một chuỗi, chứa một ký tự đặc biệt cùng với bảng chữ cái [‘A, đến‘ Z, và ‘A, với‘ Z,], đảo ngược chuỗi theo cách mà các ký tự đặc biệt không bị ảnh hưởng.
Examples:
Input: str = "a,b$c" Output: str = "c,b$a" Note that $ and , are not moved anywhere. Only subsequence "abc" is reversed Input: str = "Ab,c,de!$" Output: str = "ed,c,bA!$"
Giải pháp đơn giản: & NBSP;
- Tạo một mảng ký tự tạm thời nói temp []. & Nbsp;
- Sao chép các ký tự chữ cái từ mảng đã cho vào temp []. & Nbsp;
- Đảo ngược temp [] sử dụng thuật toán đảo ngược chuỗi tiêu chuẩn. & Nbsp;
- Bây giờ chuỗi đầu vào và tạm thời trong một vòng lặp. Bất cứ nơi nào có một ký tự chữ cái là chuỗi đầu vào, thay thế nó bằng ký tự hiện tại của temp [].
Dưới đây là việc thực hiện phương pháp trên:

Giải pháp hiệu quả: & NBSP;
Độ phức tạp về thời gian của giải pháp trên là O [N], nhưng nó đòi hỏi thêm không gian và nó thực hiện hai lần truyền tải của một chuỗi đầu vào. & Nbsp; chúng ta có thể đảo ngược với một lần đi ngang và không có thêm không gian. Dưới đây là thuật toán. & NBSP;
We can reverse with one traversal and without extra space. Below is the algorithm.
1] Let input string be 'str[]' and length of string be 'n' 2] l = 0, r = n-1 3] While l is smaller than r, do following a] If str[l] is not an alphabetic character, do l++ b] Else If str[r] is not an alphabetic character, do r-- c] Else swap str[l] and str[r]
Dưới đây là việc triển khai thuật toán trên.
