Trong chương trình này, chúng ta cần in các phần tử của mảng có mặt ở vị trí lẻ. Điều này có thể được thực hiện bằng cách lặp qua mảng và in các phần tử của mảng bằng cách tăng i lên 2 cho đến hết mảng
Trong mảng trên, các phần tử có mặt ở các vị trí lẻ là a, c và e
THUẬT TOÁN
- BƯỚC 1. Khai báo và khởi tạo mảng
- BƯỚC 2. Tính độ dài của mảng đã khai báo
- BƯỚC 3. Lặp qua mảng bằng cách khởi tạo giá trị của biến "i" thành 0 sau đó tăng giá trị của nó lên 2, i. e. , i=i+2
- BƯỚC 4. In các phần tử có mặt ở các vị trí lẻ
CHƯƠNG TRÌNH
đầu ra
Elements of given array present on odd position: 1 3 5
Đôi khi, trong khi làm việc với danh sách Python, chúng ta có thể gặp sự cố khi muốn tìm các phần tử Lẻ. Tác vụ này có thể xảy ra trong nhiều lĩnh vực như phát triển web và trong khi làm việc với Cơ sở dữ liệu. Đôi khi, chúng tôi có thể yêu cầu chỉ tìm các chỉ số của chúng. Hãy thảo luận về một số cách để tìm chỉ số của các phần tử Odd
Phương pháp #1. Sử dụng vòng lặp
Đây là phương pháp brute force mà tác vụ này có thể được thực hiện. Trong phần này, chúng tôi kiểm tra phần tử lẻ trong danh sách và nối chỉ mục của nó cho phù hợp.
