Data Structures and Algorithms Course Syllabus

A computer programme is a set of instructions for carrying out a specific task. A computer program may be required to store, retrieve, and perform computations on the data to accomplish this. A data structure is a named location where data can be stored and organized. We can write efficient and optimized computer programmes by learning data structures and algorithms (DSA).

Overview of Data Structures

A computer programme is a set of instructions for carrying out a specific task. A computer program may be required to store, retrieve, and perform computations on the data to accomplish this. A data structure is a named location where data can be stored and organized. We can write efficient and optimized computer programmes by learning data structures and algorithms (DSA).

Bit magic

The "Bit Magic" method allows us to work directly on binary data or bits, which speeds up code execution. Or

By identifying one or more bit patterns or bit numerals, you can increase the effectiveness of the algorithms.

• A brief overview of the binary and decimal number systems

• Binary number system to Decimal number system and vice versa conversion.

• Binary number addition and subtraction.

Bitwise operators

We have Arithmetic operators for working with decimal numbers and Bitwise operators for working with binary numbers.

The Bitwise operators are as follows:

• Bitwise (AND)

• Bitwise (OR)

• Bitwise (XOR)

• Bitwise (NOT)

• Right Shift

• Left Shift

Significance of these operations

• General application

• Swapping

• Even/Odd

Recursion and Backtracking

Backtracking is an algorithmic technique for recursively solving problems by attempting to build a solution incrementally, one piece at a time, removing those solutions that fail to satisfy the problem's constraints at any point in time. Backtracking is also an improvement over the brute force approach. So, the idea behind the backtracking technique is to search for a solution to a problem among all possible solutions. Initially, we begin backtracking from one possible option, and if the problem is solved with that option, we return the solution; otherwise, we backtrack and choose another option from the remaining options available.

There may also be cases where none of the options provides a solution, in which case we understand that backtracking will not provide a solution. Backtracking can also be considered a type of recursion. This is because the process of selecting a solution from the available options is repeated recursively until we either don't find a solution or reach the final state. So we can conclude that backtracking at each step eliminates options that cannot provide us with a solution and advance us to options that may provide us with a solution.

Recursion

A recursive algorithm can easily solve some problems. Recursive functions solve specific problems by calling themselves and solving smaller subproblems of the original problem. Many more recursive calls can be generated as and when needed. It is critical to understand that to end the recursion process; we must provide a specific case. As a result, we can state that the function always calls itself a simplified version of the original problem.

Arrays

An array is a collection of contiguous memory locations containing similar elements or data items of the same type. In simple terms, arrays are commonly used in computer programming to organize the same data type.

Hashing

Hashing is the process of converting one value into another based on a given key or string of characters. This is usually represented by a shorter, fixed-length value or key that represents the original string and makes it easier to find or use it.

Strings

In programming, a String is used as a data type in the same way that an int or float might be; the difference is that a String deals with textual data. It can include letters, numbers, spaces, and special characters. Strings are frequently surrounded by double quotation marks ("This is a String"). Strings can be viewed as a thread connecting various letters.
