Trong quá trình lập trình, đôi khi, chúng ta có thể có một vấn đề như vậy trong đó yêu cầu từ đầu tiên từ chuỗi phải được xóa. Những loại vấn đề này là phổ biến và người ta nên biết về giải pháp cho các vấn đề như vậy. Hãy để thảo luận về những cách nhất định trong đó vấn đề này có thể được giải quyết.

Phương pháp số 1: Sử dụng phương thức Split []

Nhiệm vụ này có thể được thực hiện bằng cách sử dụng hàm chia thực hiện phân chia các từ và tách từ đầu tiên của chuỗi với toàn bộ từ. & Nbsp;
