Hey there, tech wizards! 🌟 What exactly is an algorithm, and why should we care about its efficiency? Let's dive into this exciting world!
A step-by-step process to solve a problem; efficient algorithms use more resources to get better results.
A list of instructions to solve a problem; efficiency helps in making the algorithm more complex.
A procedure or formula for solving a problem; efficiency ensures optimal use of time and resources.
A tool for compiling programs; efficiency only affects memory usage.
Find the slowest algorithm:
O (n)
O (n^2)
O (n!)
O (2^n)
What is the time complexity of following code:
int a = 0;
for (i = 0; i < N; i++) {
for (j = N; j > i; j--) {
a = a + i + j;
}
}
O(N)
O(N*log(N))
O(N * Sqrt(N))
O(N*N)
Hey there, coding wizards! 🌟 Which of the following best compares the magical realms of Divide and Conquer vs Iterative algorithms?
Divide and Conquer uses loops to process elements sequentially, whereas Iterative algorithms use recursion to break problems into parts.
Divide and Conquer breaks problems into subproblems and solves them independently, while Iterative algorithms solve problems step by step in a loop.
Divide and Conquer is only used for sorting problems, while Iterative algorithms are used for searching.
Divide and Conquer requires more memory than Iterative algorithms because it avoids recursion.
Asher and Neha are on a quest to find the magical formula for calculating the factorial of a number n! They stumbled upon four different algorithms. Can you help them choose the correct iterative algorithm to unlock the secret of factorials?
fact = 1; for i in range(1, n+1): fact *= i
fact = 0; for i in range(1, n): fact += i
fact = n; for i in range(n-1, 0, -1): fact -= i
fact = 1; while n > 0: fact = n * fact; n += 1

Hey there, future job wizards! 🌟 Imagine Eesha, Neha, and Ria are on a mission to maximize their profits through smart job scheduling. Which clever greedy strategy should they use to conquer the Job Scheduling problem and boost their earnings?
Sort jobs by increasing deadline and pick the earliest
Sort jobs by duration and pick the shortest
Sort jobs by profit in descending order and schedule within the deadline
Pick jobs randomly and assign the latest deadline
Hey there, coding wizards! 🌟 What is the key difference between recursive and iterative algorithms? Let's help Prisha, Ria, and Aditi figure this out!
Recursive uses less memory; iterative uses more
Iterative algorithms are slower than recursive ones
Recursive uses function calls to repeat steps; iterative uses loops
Iterative algorithms are more difficult to implement than recursive ones
An algorithm is said to be correct if it produces the correct output for all possible valid inputs and terminates in a (a) amount of time.
The complexity of Binary search algorithm is
O(n)
O(log n)
O(n2)
O(n log n)
