Asked in companies
ShareChatSquadstackTata Consultancy Services (TCS)

You have been given two Strings “STR1” and “STR2” of characters. Your task is to find the length of the longest common subsequence.

A String ‘a’ is a subsequence of a String ‘b’ if ‘a’ can be obtained from ‘b’ by deletion of several (possibly, zero or all) characters. A common subsequence of two Strings is a subsequence that is common to both Strings.

You have been given a long type array/list 'arr’ of size 'n’.


It represents an elevation map wherein 'arr[i]’ denotes the elevation of the 'ith' bar.



Note :
The width of each bar is the same and is equal to 1.
Example:
Input: ‘n’ = 6, ‘arr’ = [3, 0, 0, 2, 0, 4].

Output: 10

Coding problem2

In Technical Interviewer asked Python, Project related Questions, and DBMS Questions, 1 puzzle problem. but not able to solve the Puzzle problem.

1. Puzzle

Suppose that we wish to know which stories in a 100-storey building are safe to drop eggs from, and which will cause the eggs to break on landing. What strategy should be used to drop eggs such that a total number of drops in the worst case is minimized and we find the required floor 

We may make a few assumptions: 

  • An egg that survives a fall can be used again.
  • A broken egg must be discarded.
  • The effect of a fall is the same for all eggs.
  • If an egg breaks when dropped, then it would break if dropped from a higher floor.
  • If an egg survives a fall then it would survive a shorter fall.

You have been given an unsorted array ‘ARR’.

Your task is to sort the array in such a way that the array looks like a wave array.

Example:
If the given sequence ‘ARR’ has ‘N’ elements then the sorted wave array looks like - 
‘ARR[0] >= ARR[1]’ and ‘ARR[1] <= ARR[2]’
‘ARR[2] >= ARR[3]’ and ‘ARR[3] <= ARR[4]’
‘ARR[4] >= ARR[5]’ and ‘ARR[5] <= ARR[6]’  And so on.
Note:
1. ‘ARR[0]’ must be greater than or equal to ‘ARR[1]’.

2. There can be multiple arrays that look like a wave array but you have to return only one.

3. We have an internal function that will check your solution and return 'True' in case your array is one of the solutions otherwise return 'False'.

Explanation

The given array ‘ ARR = { 4, 3, 5, 2, 3, 1, 2 } ’
The below figure is a visual representation of the given ‘ARR’ and you can see we can express ‘ARR’ in a waveform array because 
4>3 and 3<5 
5>2 and 2<3
3>1 and 1<2
And it follows the condition of wave array.
