Xóa trùng lặp trong vector c ++

Trong chương trình sau, chúng tôi lấy một vectơ số nguyên trong

Before removing duplicates:
1 2 2 3 4 4 4 5 5 
After removing duplicates:
1, 2, 3, 4, 5,

0 và loại bỏ các phần tử trùng lặp trong đó

Chúng tôi sử dụng vòng lặp For để lặp qua các phần tử của vectơ và câu lệnh If để so sánh các phần tử

Cho một mảng đã sắp xếp, nhiệm vụ là loại bỏ các phần tử trùng lặp khỏi mảng bằng STL trong C++

ví dụ

Input: arr[] = {2, 2, 2, 2, 2}
Output: arr[] = {2}

Input: arr[] = {1, 2, 2, 3, 4, 4, 4, 5, 5}
Output: arr[] = {1, 2, 3, 4, 5}

Cách tiếp cận.
Có thể loại bỏ các phần trùng lặp của mảng bằng cách sử dụng hàm unique() được cung cấp trong STL.

Dưới đây là việc thực hiện các phương pháp trên
