The interview started with an introduction. The questions asked were easy, but since I had not practiced them much, I was unable to clear the first round.

Q1: You have been given an array of strings, and you have to find the string with the maximum occurrence. If there is a tie, take the last string.

For example: Input: {cat, dog, lion, cat, lion, dog, hen, cat, dog} Output: dog

Q2: You have been given an error log file, and you have to output the ERROR logs that occur between any two dates of the month.

Q3: You have been given a text file: a) Replace the word "Amazon" with "Andy" in the first 50 lines. b) Replace the word "Amazon" with "Andy" from the 50th line till the last line.

Q4: You have been given a table named "world", where you would have to output from table "city" if the city is not null; otherwise, output the table "country".
