• Alternatively, use a counting sort algorithm to count the number of 0's and 1's and then reconstruct the array.

Heaps are data structures used to efficiently find the maximum or minimum element in a collection.

• Max heap: parent nodes are always greater than or equal to child nodes

• Min heap: parent nodes are always smaller than or equal to child nodes

• Heaps are commonly used in priority queues and sorting algorithms

• Heap operations include insert, delete, and extract max/min

• Example: An array [3, 8, 2, 5, 1, 4, 6] can be represented a

Find 3 numbers in an array where a+b=c.

• Loop through the array and check for all possible combinations of a and b.

• Use a hash table to store the values of a and b, and check if c is present in the hash table.

Fibonacci series is a sequence of numbers where each number is the sum of the two preceding ones.

• The first two numbers of the series are always 0 and 1

• The next number is the sum of the previous two numbers

• The series goes on infinitely: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ...

• Pseudo code: 1. Initialize variables a=0, b=1, c=0 2. Print a and b 3. Repeat steps 4-6 until desired number of terms 4. c=a+b 5. Pr

Algorithm for matrix multiplication

• Create a result matrix with dimensions of the two input matrices

• Iterate through each row and column of the result matrix

• For each element in the result matrix, multiply corresponding row in first matrix with corresponding column in second matrix

• Add the products obtained in the previous step to get the final value for the element
