Given an array of strings, group the strings that are anagrams of each other.
Iterate through the array of strings and sort each string alphabetically to create a key for grouping.
Use a hashmap to store the sorted string as key and the list of anagrams as value.
Return the values of the hashmap as the grouped anagrams.

The question is unclear and seems to contain errors.
The question may be referring to 'fast angle' and 'third angle projection' in technical drawing.
Fast angle refers to a type of projection where the object is viewed from an angle that is not perpendicular to any of its faces.
Third angle projection is a method of drawing 3D objects in which the object is placed in a box with three sides and projected onto a plane.

A rivet is a metal fastener used to join two or more pieces of material together permanently.
Rivets are commonly used in construction, automotive, and aerospace industries.
They are inserted into pre-drilled holes and then deformed to hold the materials together.
Rivets can be made of various materials including aluminum, steel, and copper.
They are often used in place of screws or bolts when a permanent joint is required...
The number of cutting angles in a reamer varies depending on the type and size of the reamer.
The number of cutting angles can range from 2 to 6.
The cutting angles are designed to remove material from the workpiece as the reamer rotates.
The cutting angles can be straight or spiral, and can be symmetrical or asymmetrical.
The number and angle of the cutting edges can affect the surface finish and accuracy of the hole.

Drill bits can have various cutting angles depending on their purpose and material.
The most common cutting angle for general purpose drill bits is 118 degrees.
Drill bits for harder materials like metal may have a sharper angle of 135 degrees.
Masonry drill bits have a flatter angle of 90 degrees to prevent cracking of the material.
The cutting angle affects the efficiency and precision of the drilling process.
Drill bits are made by various manufacturers using different materials and designs.
Drill bits can be made from high-speed steel, cobalt, carbide, or diamond.
Manufacturers include DeWalt, Bosch, Milwaukee, and Irwin.
The design of the drill bit can vary depending on the intended use, such as twist bits, spade bits, or hole saws.
The number of cutting files depends on the project requirements and design complexity.
The number of cutting files can range from a few to hundreds or even thousands.
It also depends on the type of cutting machine being used.
For example, a laser cutting machine may require different files than a CNC router.
The number of cutting files can also vary based on the material being cut and its thickness.

Projects are specific tasks or assignments that require a set of skills and resources to complete.
Projects are temporary in nature with a defined start and end date.
They typically have specific goals, deliverables, and constraints.
Projects require a team of individuals with different roles and responsibilities.
Examples: Developing a mobile app, implementing a new software system, conducting a research study.

RISC (Reduced Instruction Set Computing) has a smaller set of simple instructions, while CISC (Complex Instruction Set Computing) has a larger set of complex instructions.
RISC processors have simpler instructions that can be executed in a single clock cycle, making them faster.
CISC processors have more complex instructions that may require multiple clock cycles to execute.
RISC architectures typically have a smaller chi...
ADC converts analog signals into digital data by sampling the input signal at regular intervals.
ADC samples the input signal at regular intervals
It quantizes the sampled values into discrete digital values
The resolution of ADC determines the number of possible digital values
Common types of ADC include successive approximation ADC and delta-sigma ADC
I applied via Campus Placement and was interviewed in Sep 2021. There were 4 interview rounds.
Sorting algorithm is a method of arranging elements in a specific order.
Common sorting algorithms include bubble sort, insertion sort, selection sort, merge sort, quick sort, and heap sort.
The choice of sorting algorithm depends on the size of the data set, the data type, and the desired time complexity.
Sorting algorithms can be implemented in various programming languages such as Java, Python, and C++.
Reverse a string and find a duplicate in an array of strings.
To reverse a string, we can use the built-in reverse() method or loop through the string and append each character to a new string in reverse order.
To find a duplicate in an array of strings, we can use a hash table to keep track of the frequency of each string and return the first string with a frequency greater than 1.
I was interviewed in Oct 2021.

The cut command in Linux is used to extract sections from each line of input.
Used to cut out specific sections of text from a file or input stream
Can specify the delimiter used to separate fields
Options include -c for characters, -f for fields, and -d to specify the delimiter
Example: cut -d',' -f1,3 file.txt
The Find command in Linux is used to search for files and directories based on specified criteria.
Used to search for files and directories in a specified directory
Criteria can include file name, size, permissions, and more
Can be combined with other commands like -exec to perform actions on found files
