The document contains code for three string methods: Sacar_Palabra extracts the first word of a string, EliminarPrimera removes the first word from a string, and EliminarIesimo removes the word at a given index from a string. Sacar_Palabra uses a while loop to add characters to an auxiliary string until it reaches a space. EliminarPrimera uses while loops to skip over the first word and concatenate the remaining words into a new string. EliminarIesimo calls the other methods in a while loop to either add the extracted word or remove the word at the given index and increment the counter.
