#include<bits/stdc++.h>
using namespace std;
 
void func(char* str2, char* str1)
{
int m = strlen(str2);
int n = strlen(str1);
for (int i = 0; i <= n - m; i++)
{
int j;
 
 
for (j = 0; j < m; j++)
if (str1[i + j] != str2[j])
break;
 
if (j == m)
cout << i << endl;
}
}
 
int main()
{
char str1[] = "1253234";
char str2[] = "323";
func(str2, str1);
return 0;
}
a) 1
b) 2
c) 3
d) 4
