在本文中,我们将解决从给定字符串中删除给定单词的问题。例如 -
Input : str = “remove a given word ”, word = “ remove ” Output : “ a given word ” Input : str = “ god is everywhere ”, word = “ is ” Output : “ god everywhere ”
例如,我们可以使用一种简单的方法从字符串中删除单词。
#include <bits/stdc++.h> using namespace std; int remove_word (string str, char word[]) { char matrix[10][30]; int i = 0, j = 0, k = 0, len1 = 0, len2 = 0; // putting each word of string into the rows of the 2-D matrix. for (i = 0; str[i] != '\0'; i++) { if (str[i] == ' ') { matrix[k][j] = '\0'; k++; j = 0; }else{ matrix[k][j] = str[i]; j++; } } // looking for the word in a given string and putting a null character when the word is found. matrix[k][j] = '\0'; j = 0; for (i = 0; i < k + 1; i++) { if (strcmp (matrix[i], word) == 0) { matrix[i][j] = '\0'; } } j = 0; // printing the reordered string. for (i = 0; i < k + 1; i++){ if (matrix[i][j] == '\0') continue; else cout << matrix[i] << " "; } cout << "\n"; } int main () { char str1[] = "remove a given word", word1[] = "remove"; char str2[] = "god is everywhere", word2[]="is"; // calling a function to remove a word from a string and print it. remove_word (str1, word1); remove_word (str2, word2); return 0; }
a given word god everywhere
本文讨论了删除给定单词来自字符串,我们通过将字符串存储在二维矩阵中然后用空值替换该单词来解决问题。我们使用 C++ 代码解决了这个问题。但是,我们可以使用任何其他语言(例如 C、Java、Python 等)解决相同的问题。希望本文对您有所帮助。
