Example 2:

Input: s = "here" Output: "here" 

Example 3:

Input: s = "LOVELY" Output: "lovely" 

Constraints:

• 1 <= s.length <= 100
• s consists of printable ASCII characters.

给你一个字符串 s ，将该字符串中的大写字母转换成相同的小写字母，返回新的字符串。

• 简单题，将字符串中的大写字母转换成小写字母。

functoLowerCase(sstring) string { runes:= [] rune(s) diff:='a'-'A'fori:=0; i<len(s); i++ { ifrunes[i] >='A'&&runes[i] <='Z' { runes[i] +=diff } } returnstring(runes) }
