Round 3: Technical Interview
Explain your written code of previous round. If any error,find it,correct it. If your code is not
optimize and not space efficient then Give optimize & efficient solution of your written code.
Interviewer is very friendly, he only check your explanation process or optimization techniques.
After the written code explanation, he ask 2 coding question:-
1.) Merge an array of size n into another array of size m+n
2.) Given a text string and a sample string. Find if the characters of the sample string is in the same
order in the text string.
Eg:-
TextString: abcnjhgahgjhfhaljhrkhgrbhjbevfho
