Fastenal visited our campus for Full Time Recruitment. There were 3 rounds in total.
Difficulty Level: Medium
- Online Coding Round
- Technical Round 1
- HR
Round 1: Online Coding round (90 Minutes)
Coding Questions(30 Mins)
50 MCQ (60 Mins)
There were 2 Coding Questions based on String.
1. String Letter Search: You are given a String X and a string containing single character Y. Your task is to find the largest distance between any two occurrences of the character Y in string X.
The Distance is defined by the no of distinct characters between any two occurrences of char Y in string X (Exclude whitespaces).
If there is no occurrences or only one occurrences of the given character, the function should return -1.
Example:
Input1: my name is ranary
Input2: a
Output: 7
2. Passwords: Find how many Distinct passwords are there in total:
Details of password: Each password is a string of characters from a to z (small letters).
Two passwords say Pass1 and Pass2, are said to be same if Pass2 can be obtained by swapping the ith character with jth character in Pass1 where (i+j)%2==0.
Example:
Input1: 2
Input2: {abcd,bcad}
Output: 2
“bcad” cannot be obtained from “abcd” under given conditions. Hence, 2 distinct passwords.
