   • Software Engineering
   • DBMS

   In the core subjects, they want basic knowledge on the subjects.

3. Coding question:

   • Given a string str=”example*xyz*jio”; We have to split the given string by * and find the size of the result and time complexity of algorithm used.

Total Time of interview: 45-50 mins. 

Code:

#include<bits/stdc++.h>
using namespace std;
int main()
{
   //given string str
   string str=”geeksforgeeks@2021@jio”;
   string s=””;  //empty string
vector<string> v;   //string array
int l=str.length();
int count=0;   // no. of @ ->seperators
for(int i=0;i<l;i++)
{
    if(str[i]==’@’)
    {
        v.push_back(s);
        s=””;
        count++;
    }
    else
    {
        s+=str[i];
    }
}
v.push_back(s);
cout<<“No. of substrings seperated by @  “<<count+1<<endl;
cout<<“Substrings are:\n\n”;
for(string i: v )
cout<<i<<endl;
cout<<“\n\nresult size: \n”;
cout<<“Size of “<<count+1<<” substrings
    + size of “<<count +1<<” pointers pointing sunstrings\n”;
return 0;
}

Finally, they selected 13 students from our Campus.
