- Q1. Find a number which occurs odd number of times and all number occurs even number of times
- Ans.
Find an odd occurring number among even occurring numbers.
Use XOR operation to cancel out even occurring numbers and get the odd occurring number.
Iterate through the array and XOR each element with the result variable.
The final result will be the odd occurring number.
- Q2. Some discussion about my minor project
- Q3. Spiral order of binary tree and mattrix, print it
- Ans.
Print the spiral order of a binary tree and matrix.
For binary tree, use level order traversal and alternate direction for each level.
For matrix, use four pointers to traverse in spiral order.
Example for binary tree: 1 -> 2 -> 3 -> 4 -> 5 -> 6 -> 7 -> 8 -> 9
Example for matrix: 1 2 3 4 -> 8 7 6 5 -> 9 10 11 12 -> 16 15 14 13
- Q4. Some question about os,dbms
- Q5. Find pair which have a given sum in a given array
- Ans.
Finding pairs in an array with a given sum.
Iterate through the array and for each element, check if the difference between the given sum and the element exists in the array.
Use a hash table to store the elements of the array and their indices for faster lookup.
If there are multiple pairs with the same sum, return any one of them.
If no pair is found, return null or an empty array.
- Q6. Find total number of k element which have a given avg in a given array in minimum time complexity
- Ans.
Find total number of k element with given avg in an array in minimum time complexity.
Use sliding window technique to traverse the array in O(n) time complexity.
Maintain a sum variable to keep track of the sum of elements in the window.
If the sum of elements in the window is equal to k times the given avg, increment the count.
Move the window by subtracting the first element and adding the next element in the array.
- Q7. Print all elements which in not boundary element in a given binary tree
- Ans.
Printing non-boundary elements of a binary tree
Traverse the tree in any order (preorder, inorder, postorder)
Check if the current node is not a boundary node (not the first or last node in its level)
If it is not a boundary node, print its value
Recursively traverse its left and right subtrees
- Q8. Then some question about process synchronisation,error vs exception,and then 2-3 hr question

- Q2. Delete a node from linked list when we are given a reference to the node. But the head pointer is not given.
- Ans.
To delete a node from a linked list when only given a reference to the node, we can copy the data of the next node to the given node and delete the next node.
Copy the data of the next node to the given node
Update the next pointer of the given node to skip the next node
Delete the next node
