All rounds Pen-paper coding.
1. Given a file, Print All words which end with “ing” with their frequency
Condition: No inbuilt string function like substr split contains allowed.
character by character need to take input, when space comes, check whether last 3 chars “ing”. If yes then from start to that index, add that word to hashmap(if new word), otherwise increase frequency of that word.
after space adjust start index and iterate.
at last when whole file input taken, iterate through Hashmap and print key and value.
2. Given a big string (contains numbers) and a divisor, Print all Subarray with 2 to 5 size which is exactly divided by divisor.
Ex: 1234804 and divisor 12,
From all these subarrays 12, 123, 1234, 12348, 23, 234, 2348, 23480, 34, 348, 3480, 34804, 48, 480, 4804, 80, 804, 04 those which are divided by 12, need to print those.
Overriding and Polymorphism conceptual questions.
1. You are given 100 normal coins and 1 faulty coin

Only 1st 2 conditions are there.

ans: 6(0, 3 -> 0, 2 -> 1, 2 -> 2, 2 -> 2, 3 -> 3, 3)
Cherry in the glass puzzle
4th round with Senior director
Que: Given 13-MAR-2019 and n=40 means after adding 40 days to input date, we have 22-APR-2019.
No inbuilt Date function allowed.
Need to consider all cases, leap year or not, Monthwise days mapping(1->31, 4->30 etc), MAR->3, APR-4 mapping, 3-> MAR, 5->MAY mapping.
After that told that HR Will call you.
After Rejected from 20 different companies, got selected.
NEVER QUIT. APNA TIME AAYEGA.
