ARRAYS
1. Introduction to Arrays
Linear Search Algorithm
• Explains how to search for an element in an array
by iterating through it one by one.
Triplet Sum and Sorting
• Discusses the problem of nding three elements
in an array that add up to a given sum, and the
role of sorting in solving this problem.
Cracking Interview Questions
• Provides tips and tricks for answering common
array-related questions in technical interviews.
Passing Arrays to Functions
• Discusses how to pass arrays as arguments to
functions, including how to handle updates to the
array within the function.
Finding Unique and Duplicate Elements
• Explains how to nd unique and duplicate
elements in an array, and the role of data
structures such as sets in solving this problem.
Array Sum and Power of 2
• Discusses the relationship between the sum of an
array and the power of 2, and how to ef ciency
determine if a sum can be represented as a power
of 2.
Reversing an Array
• Explains how to reverse the elements in an array,
including different approaches and their time
complexity.
fi fi fi
, Array Intersection and Pair Sum
• Discusses the problem of nding common
elements in two arrays and how to nd a pair of
elements in an array that add up to a given sum
Declaring and Initializing Arrays
• Explains how to declare and initialize arrays in
different programming languages
Accessing Array Elements using Index
• Discusses how to access array elements using
index and the rules and constraints related to
indexing in different programming languages
Finding Maximum and Minimum Values in Arrays
• Explains how to nd the maximum and minimum
values in an array, and how to handle cases when
multiple elements have the same maximum or
minimum value
Understanding Array Scope and Updates
• Discusses the concept of array scope and how
arrays can be updated within different scopes and
contexts
Working with Multi-Dimensional Arrays
• Explains how to work with multi-dimensional
arrays, including how to declare, initialize, access
and update their elements, and their time and
space complexity.
