Dada una String y una Palabra, la tarea es eliminar esa Palabra de la String.
Ejemplos:
Input: String = "Geeks For Geeks", Word = "For" Output: "Geeks Geeks" Input: String = "A computer Science Portal", Word = "Geeks" Output: "A computer Science Portal"
Enfoque: en Java, esto se puede hacer usando el método String replaceAll reemplazando la palabra dada con un espacio en blanco.
A continuación se muestra la solución al problema anterior:
C++
// C++ program to remove
// a given word from a string
#include <bits/stdc++.h>
using namespace std;
string removeWord(string str, string word)
{
// Check if the word is present in string
// If found, remove it using removeAll()
if (str.find(word) != string::npos)
{
size_t p = -1;
// To cover the case
// if the word is at the
// beginning of the string
// or anywhere in the middle
string tempWord = word + " ";
while ((p = str.find(word)) != string::npos)
str.replace(p, tempWord.length(), "");
// To cover the edge case
// if the word is at the
// end of the string
tempWord = " " + word;
while ((p = str.find(word)) != string::npos)
str.replace(p, tempWord.length(), "");
}
// Return the resultant string
return str;
}
// Driver Code
int main(int argc, char const *argv[])
{
// Test Case 1:
// If the word is in the middle
string string1 = "Geeks for Geeks.";
string word1 = "for";
// Test Case 2:
// If the word is at the beginning
string string2 = "for Geeks Geeks.";
string word2 = "for";
// Test Case 3:
// If the word is at the end
string string3 = "Geeks Geeks for.";
string word3 = "for";
// Test Case 4:
// If the word is not present
string string4 = "A computer Science Portal.";
string word4 = "Geeks";
// Test case 1
cout << "String: " << string1 << "\nWord: "
<< word1 << "\nResult String: "
<< removeWord(string1, word1) << endl;
// Test case 2
cout << "\nString: " << string2 << "\nWord: "
<< word2 << "\nResult String: "
<< removeWord(string2, word2) << endl;
// Test case 3
cout << "\nString: " << string3 << "\nWord: "
<< word3 << "\nResult String: "
<< removeWord(string3, word3) << endl;
// Test case 4
cout << "\nString: " << string4 << "\nWord: "
<< word4 << "\nResult String: "
<< removeWord(string4, word4) << endl;
return 0;
