Dada una string, convierta los caracteres de la string en mayúsculas y minúsculas, es decir, si un carácter está en minúsculas, conviértalo en mayúsculas y viceversa.
Ejemplos:
C++
// CPP program to Convert characters
// of a string to opposite case
#include <iostream>
using namespace std;
// Function to convert characters
// of a string to opposite case
void convertOpposite(string& str)
{
int ln = str.length();
// Conversion according to ASCII values
for (int i = 0; i < ln; i++) {
if (str[i] >= 'a' && str[i] <= 'z')
// Convert lowercase to uppercase
str[i] = str[i] - 32;
else if (str[i] >= 'A' && str[i] <= 'Z')
// Convert uppercase to lowercase
str[i] = str[i] + 32;
}
}
// Driver function
int main()
{
string str = "GeEkSfOrGeEkS";
// Calling the Function
convertOpposite(str);
cout << str;
return 0;
}
Java
// Java program to Convert characters
// of a string to opposite case
class Test {
// Method to convert characters
// of a string to opposite case
static void convertOpposite(StringBuffer str)
{
int ln = str.length();
// Conversion using predefined methods
for (int i = 0; i < ln; i++) {
Character c = str.charAt(i);
if (Character.isLowerCase(c))
str.replace(i, i + 1,
Character.toUpperCase(c) + "");
else
str.replace(i, i + 1,
Character.toLowerCase(c) + "");
}
}
public static void main(String[] args)
{
StringBuffer str
= new StringBuffer("GeEkSfOrGeEkS");
// Calling the Method
convertOpposite(str);
System.out.println(str);
}
}
