Duration: 40-70 minutes
Round: Test
Experience: There were four coding questions. We just had to write the functions. Any programming language even pseudo code was allowed. Q1. Convert a decimal number into fraction (e.g. input is 0.5 (float) output will be “1/2” (string)) Q2. There is a question which is slightly modified version of maximum-subarray problem. Q3. Given n. Generate all numbers with number of digits equal to n, such that the digit to the right is greater than the left digit (ai+1 > ai). E.g. if n=3 (123,124,125,......129,234,.....789) Q4. You can swap only two consecutive elements. You have to show all steps to convert a string into another string (both strings will be anagrams of each other). E.g. GUM to MUGGUM
GMU
MGU
MUG

- Q1. Questions were from resume only. They will ask about any project and various technologies in it
- Q2. Given and Array of A[1..n] bits, find the length of longest consecutive substring of 0 and 1 such that number of 0s and 1s are equal?
- Ans.
Find length of longest consecutive substring of 0 and 1 with equal count in given array of bits.
Create a prefix array to store the difference between count of 0s and 1s till each index.
Find the first and last occurrence of each unique value in prefix array.
Calculate the length of the subarray between first and last occurrence of each unique value.
Return the maximum length of subarray with equal count of 0s and 1s.
- Q3. Given two sequences of length N, how to find the max window of matching patterns. The patterns can be mutated
- Ans.
To find max window of matching patterns between two sequences of length N with mutated patterns.
Create a sliding window of size N and traverse both sequences simultaneously.
Check for matching patterns in the window and keep track of the maximum window with matching patterns.
Use a hash table to keep track of mutated patterns.
If a pattern is mutated, update the hash table and check if it matches with the other sequence.
R...
- Q4. For example, seq1 = “ABCDEFG”, seq2 = “DBCAPFG”, then the max window is 4. (ABCD from seq1 and DBCA from seq2)
- Ans.
Find the maximum window size of common substring in two given sequences.
Use dynamic programming to find the length of longest common substring.
Slide a window of that length over both sequences to find the common substring.
If no common substring is found, decrease the window size and repeat.
- Q5. How do you rotate a string of length n word by word with constant extra space in linear time ?
- Ans.
Rotate a string of length n word by word with constant extra space in linear time.
Reverse the entire string
Reverse each word in the string
Handle the last word separately
Time complexity: O(n)
Space complexity: O(1)
