   int n2 = sizeof(str2)/sizeof(str2[0]);
   printf("n1 = %d, n2 = %d", n1, n2);
   return 0;
}

16. Predict the Output

After four days, got a call for Round 2,
Round - 2 (2 hour):

• complete coding round
• Algorithm question
• 5 questions starting from easy to medium to hard(only last question was hard) level leetcode problems.
• 5th question was taken directly from Leetcode #149 Max Points on a Line

Round -3 (2 hours)

• On the same day, they called for Round-3, in which there was 1 OOPs based long problem.

Thank You.
