  for (i=0; i<n-1; i++) {
    for (j=i+1; j<n; j++) {
      int s = tolower(string[i]) - tolower(string[j]);
      if ( s == 0 ) { 
        // letters are the same... now watch out for case 
        s = string[i] - string[j]; 
      }
      if (s > 0) {
        temp = string[i]; string[i] = string[j];

Technical Round 2

  1. Explain your projects?

  2. Memory representation of const char *a & const * char a & which will give error?

  3. Write a program to do a+b and a-b using different threads.

  4. Write a program to do a+b and a-b using different process (Parent and child process).

  5. Write a SQL query to find emp_id,emp_name,emp_manager_name from following table: (employee is table name) | Emp_id | Emp_name | Emp_manager_id | |--------|-----------|-----------------| | 1 | abc | 3 | | 2 | xyz | 3 | | 3 | pqr | 4 | | 4 | def | null |
