  int temp;
 for(int i=0;S[i]!='\0';i++)
    {
        int j=0;
        if(S[i]==T[j])
        {
             temp=i;
            while(S[i]==T[j])
            {
                i++;
                j++;
            }
 
            if(T[j]=='\0')
            {
                return temp;
                
            }
            else
            {
                i=temp;
                temp=0;
            }
