- Q1. Find Maximum sub sequence sum in an array ?
- Ans.
Maximum sub sequence sum in an array
Use Kadane's algorithm
Initialize max_so_far and max_ending_here to 0
Iterate through the array and update max_ending_here and max_so_far
Return max_so_far
- Q2. What do you understand by the endianness of the system ? How do you find out the the type of endianness ?
- Ans.
Endianness refers to the byte order of a system. It determines how multi-byte data types are stored in memory.
Little-endian systems store the least significant byte first, while big-endian systems store the most significant byte first.
Endianness can affect the way data is transmitted between systems.
To determine the endianness of a system, you can use the byte order mark (BOM) or write a test program that checks the by...
- Q3. Sort an array which consists of 0's and 1's only
- Ans.
Sort an array of 0's and 1's only.
Use two pointers, one at the beginning and one at the end of the array.
Swap 0's from the beginning with 1's from the end until the pointers meet.
Alternatively, use a counting sort algorithm to count the number of 0's and 1's and then reconstruct the array.
- Q4. A question on applications of minimum spanning tree, apply prim's or kruskal's algorithm
- Q5. What do you understand by Heaps, max and min heaps ?
- Ans.
Heaps are data structures used to efficiently find the maximum or minimum element in a collection.
Max heap: parent nodes are always greater than or equal to child nodes
Min heap: parent nodes are always smaller than or equal to child nodes
Heaps are commonly used in priority queues and sorting algorithms
Heap operations include insert, delete, and extract max/min
Example: An array [3, 8, 2, 5, 1, 4, 6] can be represented a
- Q6. What do you understand by hashing ? questions on application of hashing
- Q7. Find 3 nos a,b and c in an array where a+b = c
- Ans.
Find 3 numbers in an array where a+b=c.
Loop through the array and check for all possible combinations of a and b.
Use a hash table to store the values of a and b, and check if c is present in the hash table.
Sort the array and use two pointers to find a and b, and then check if their sum equals c.
