  • Print all sub-arrays with 0 sum

    Given an array of integers, it is often required to find all sub-arrays with a sum equal to 0. This problem can be solved using the hashing approach. Approach: Hashing The hashing approach involves storing the cumulative sum of the elements in a hash table. If a cumulative sum repeats itself, it indicates that there…

  • what is backtracking?

    Backtracking is an algorithmic technique for solving problems by trying out different solutions and undoing them if they fail to reach the desired outcome. It is used to solve problems that involve searching through a large number of possible solutions. Backtracking works by incrementally building a potential solution, and then abandoning the partial solution as…

  • Binary search in Go

    Here is an example implementation of binary search in Go: In this implementation, binarySearch() function takes two arguments, a sorted integer slice input, and a target element to search for. It then performs the binary search algorithm on the slice to find the index of the target element. If the target is found, it returns…
