Dada la string, la tarea es poner en mayúscula el primer y último carácter de cada palabra en una string.
Ejemplos:
Input: Geeks for geeks Output: GeekS FoR GeekS Input: Geeksforgeeks is best Output: GeeksforgeekS IS BesT
Acercarse
- Crear una array de caracteres de la string
- Ejecute un bucle desde la primera letra hasta la última letra.
- Comprobar si el carácter es el principio o el final de la palabra
- Compruebe si el carácter es una letra minúscula.
- En caso afirmativo, escriba en mayúscula el carácter de la string.
A continuación se muestra la implementación del enfoque anterior.
