C++ and DSA Foundation Course - Binary Search Problems - 1 | Lecture-45 | C++ And DSA Foundation course

Now that we have learned the Binary search algorithm and its implementation in the previous lecture, let us move to the next step of problem-solving for better understanding. Here, Sanket Sir is going to solve some problems using Binary search as the base. He will discuss and build the approach to solution from Brute force to optimal binary search. So do not miss this! Follow us to prepare for the college exams, interviews and placements with immaculate problem-solving and coding skills. See you in the class !! Are you finding the classes helpful?

Find the first and last position of the given 'target' element in a sorted array 44:10 - Coding implementation 51:41 - A rotated sorted array is a sorted array on which a rotation operation has been performed some number of times 01:06:43 - Coding implementation 01:11:55 - Given the rotated sorted array of integers, which contains distinct elements, and a target value, return the index of target if it is in the array otherwise return -1. 01:25:30 - Coding Implementation 01:31:34 - Search an element in a rotated sorted array with duplicate elements, return 1 if it is found, otherwise return -1. 01:37:31 - Summary #DSA #ProblemSolving #BinarySearch #Lecture44 #DataStructures #CodingChallenges #Debugging #LogicalThinking #PWSkills #PhysicsWallah #CollegeWallah
