Different types of brick bonds used in construction.
Stretcher bond: Most common bond, with bricks laid lengthwise.
Header bond: Bricks laid widthwise with headers facing outwards.
English bond: Alternating courses of headers and stretchers.
Flemish bond: Alternating headers and stretchers in each course.
Stack bond: Bricks stacked directly on top of each other.
Basket weave bond: Bricks laid in a crisscross pattern.

Both fly ash and cement have their own advantages and disadvantages.
Fly ash is a byproduct of coal combustion and is eco-friendly.
Cement is a binding material and is essential for construction.
Fly ash reduces the amount of cement needed in concrete mixtures.
Cement provides strength and durability to concrete structures.
The choice between fly ash and cement depends on the specific requirements of the project.
Specific gravity of soil is the ratio of the mass of a given volume of soil solids to the mass of an equal volume of distilled water.
Specific gravity is a dimensionless quantity.
It is used to determine the void ratio, porosity, and degree of saturation of soil.
It is also used to classify soils based on their mineral composition.
The specific gravity of soil ranges from 2.0 to 2.8.
It can be determined using various metho...
The length of reflection strips on engineering jackets varies depending on the safety standards and regulations of the industry.
The length of the strips should be enough to provide visibility in low-light conditions.
The strips should be placed strategically on the jacket to ensure maximum visibility.
The length and placement of the strips may vary depending on the type of jacket and the industry it is used in.

Modular size of brick refers to the standard size of bricks used in construction.
Modular size of brick is 190mm x 90mm x 90mm.
It is the most commonly used size in construction.
Modular size bricks are preferred due to their uniformity and ease of use in construction.
Other sizes of bricks include non-modular sizes like 230mm x 110mm x 70mm and 290mm x 90mm x 90mm.
The size of bricks can vary depending on the country and r

Merge Sort is a divide and conquer algorithm that sorts an array by dividing it into two halves, sorting them separately, and then merging the sorted halves.
Divide the array into two halves
Recursively sort the two halves
Merge the sorted halves
Find pairs of integers in a BST whose sum is equal to a given number.
Traverse the BST and store the values in a hash set.
For each node, check if (X - node.value) exists in the hash set.
If yes, add the pair (node.value, X - node.value) to the result.
Continue traversal until all nodes are processed.
Merge overlapping time intervals into mutually exclusive intervals.
Sort the intervals based on their start time.
Iterate through the intervals and merge overlapping intervals.
Output the mutually exclusive intervals.
Example: [(1,3), (2,6), (8,10), (15,18)] -> [(1,6), (8,10), (15,18)]
Different types of hashing and alternative for Linear Chaining
Different types of hashing include division, multiplication, and universal hashing
Alternative for Linear Chaining is Open Addressing
Open Addressing includes Linear Probing, Quadratic Probing, and Double Hashing
An AVL tree is a self-balancing binary search tree where the heights of the left and right subtrees differ by at most one.
AVL tree is a binary search tree with additional balance factor for each node.
The balance factor is the difference between the heights of the left and right subtrees.
Insertion and deletion operations in AVL tree maintain the balance factor to ensure the tree remains balanced.
Rotations are performed ...
Find the minimum number of squares whose sum equals to a given number n.
Use dynamic programming to solve the problem efficiently.
Start with finding the square root of n and check if it is a perfect square.
If not, then try to find the minimum number of squares required for the remaining number.
Repeat the process until the remaining number becomes 0.
Return the minimum number of squares required for the given number n.
Insertion sort for a singly linked list.
Traverse the list and compare each node with the previous nodes
If the current node is smaller, swap it with the previous node
Repeat until the end of the list is reached
Time complexity is O(n^2)
