How to efficiently remove every occurrence of one string inside another
I have two strings and want to remove every occurrence of the second string inside the first one starting from the beginning of the first string and as if each occurrence was removed immediately. I would like to do so in C in a time-efficient way, i.e. probably with the lowest number of comparisons and include/copy actions.

completely reworked the question to contain the core idea and ask for an efficient algorithm/C implementation, removed the code example because it was not related to the core problem
How do you remove every occurrence of the second string inside the first one?
- How to efficiently remove every occurrence of one string inside another
I came across a sample practice question on the internet. How do you remove every occurence of the second string inside the first one?> Write a program that reads two strings of less than 30 characters and removesevery occurrence of the second string inside the first one. After each removal, theremaining part of the first string should be shifted to the left, a number of placesequal to the characters of the second string. The program should display the firststring, before it ends. Here's my progress so far:```#include <stdio.h>#include <stdlib.h>#include <string.h>char *new_string(char *, char *);int main(void){char *str1, *str2, *ptr3;str1 = malloc(30 * sizeof(char));printf("Enter first text: ");fgets(str1, 30, stdin);str2 = malloc(30 * sizeof(char));printf("Enter second text: ");fgets(str2, 30, stdin);ptr3 = new_string(str1, str2);if (ptr3 == NULL)printf("String 1 has been removed totally");else {printf("");}return 0;}char *new_string(char *str1, char *str2){//need some help here}```
