Question

Write a program to remove the charactes whose consecutive length is exactly equal to the input given number

Answer 1

// C++ implementation of above approach

#include <bits/stdc++.h>

using namespace std;

// function to calculate minimum

// characters to replace

int replace(string A, string B)

{

int n = A.length(), m = B.length();

int count = 0, i, j;

for (i = 0; i < n; i++) {

for (j = 0; j < m; j++) {

// mismatch occurs

if (A[i + j] != B[j])

break;

}

// if all characters matched, i.e,

// there is a substring of 'a' which

// is same as string 'b'

if (j == m) {

count++;

// increment i to index m-1 such that

// minimum characters are replaced

// in 'a'

i += m - 1;

}

}

return count;

}

// Driver Code

int main()

{

string str1 = "aaaaaaaa";

string str2 = "aaa";

cout << replace(str1 , str2);

return 0;

}

Plz mark me as brainiest...
