Hướng dẫn determine if a string has all unique characters in c++ - xác định xem một chuỗi có tất cả các ký tự duy nhất trong C++

Cho một chuỗi, xác định xem chuỗi có tất cả các ký tự duy nhất không.

Ví dụ: & nbsp; & nbsp;

```Input : abcd10jk
Output : true

Input : hutg9mnd!nk9
Output : false```

Cách tiếp cận 1 - Kỹ thuật lực lượng vũ phu: Chạy 2 vòng với biến I và J. So sánh str [i] và str [j]. Nếu họ trở nên bình đẳng tại bất kỳ điểm nào, hãy trả lại sai. & NBSP;: Run 2 loops with variable i and j. Compare str[i] and str[j]. If they become equal at any point, return false.

: This approach assumes ASCII char set(8 bits). The idea is to maintain a boolean array for the characters. The 256 indices represent 256 characters. All the array elements are initially set to false. As we iterate over the string, set true at the index equal to the int value of the character. If at any time, we encounter that the array value is already true, it means the character with that int value is repeated.

Độ phức tạp về thời gian: O (n) & nbsp;: O(n)

Không gian phụ trợ: O (n) O(n)

Cách tiếp cận 4-Không có cấu trúc dữ liệu bổ sung: Cách tiếp cận có giá trị đối với các chuỗi có bảng chữ cái dưới dạng A-Z. Cách tiếp cận này là một chút khó khăn. Thay vì duy trì một mảng boolean, chúng tôi duy trì giá trị số nguyên gọi là trình kiểm tra (32 bit). Khi chúng tôi lặp lại chuỗi, chúng tôi tìm thấy giá trị INT của ký tự đối với 'A' với câu lệnh int bitatindex = str.charat (i)-'a'; & nbsp; thì bit tại giá trị int đó được đặt thành 1 với câu lệnh 1 The approach is valid for strings having alphabet as a-z. This approach is a little tricky. Instead of maintaining a boolean array, we maintain an integer value called checker(32 bits). As we iterate over the string, we find the int value of the character with respect to ‘a’ with the statement int bitAtIndex = str.charAt(i)-‘a’;
Then the bit at that int value is set to 1 with the statement 1 << bitAtIndex
Now, if this bit is already set in the checker, the bit AND operation would make the checker > 0. Return false in this case.
Else Update checker to make the bit 1 at that index with the statement checker = checker | (1 <
