轉變小寫
參考及出處網站:Leetcode
思路:我的想法是從ASC||碼著手
我的想法是把他轉成ASC|| 再加上32 再轉回char;
public static string ToLowerCase(string str)
{
string capitalText = str;
int cNum = 0;
string lowercaseText = "";
foreach (char c in capitalText)
{
cNum = Convert.ToInt32(c);
if (cNum >= 65 && cNum <= 90)
{
cNum += 32;
}
char character = (char)cNum;
lowercaseText += character;
}
return lowercaseText;
}
但看下來 其實這樣解好像不優~
Runtime: 100 ms, faster than 56.42% of C# online submissions for To Lower Case.
Memory Usage: 7.7 MB, less than 3.98% of C# online submissions for To Lower Case.
主要是做我的學習筆記
