题目大意:若字符串首字符为大写字母及不改变,若为小写字母,将其改变成大写即可。
解题思路:相当水的一道题,不需要思路。
注意事项:仅需针对首字符操作即可

以下为解题代码(java实现)
import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Scanner scanner = new Scanner(System.in);
		String string = scanner.nextLine();
		char first = string.charAt(0);
		if(first >= 'a' && first <= 'z'){
			System.out.println(string.substring(0,1).toUpperCase() + string.substring(1));
		}else{
			System.out.println(string);
		}
	}
}
