Find 3 contigious elements of an array with sum equals zero with example in c,c++,python and java
Here are solutions for finding three contiguous elements in an array whose sum equals zero in C, C++, Python, and Java: These solutions iterate over the array and check the sum of each group of three contiguous elements. If the sum is zero, the triplet is found and printed; otherwise, the function continues to search.…

Find 3 elements of an array with sum equals zero with example in c,c++,python and java
Here are solutions for finding three elements in an array whose sum equals zero in C, C++, Python, and Java: These solutions iterate over the array using nested loops and use different techniques to find three elements whose sum is zero. The C and C++ solutions use three nested loops and an unordered set, while…

Find 2 elements of an array with sum equals zero with example in c,c++,python and java
I’ll provide solutions for finding two elements in an array whose sum equals zero in C, C++, Python, and Java. These solutions iterate over the array and use different techniques to find two elements whose sum is zero. The C and C++ solutions use nested loops and an unordered set, while the Python and Java…

write travelling salesman problem solution with example in c++
Here’s an example of solving the Traveling Salesman Problem (TSP) using the Nearest Neighbor Algorithm in C++: In this example, we have a graph representing the distances between cities. The findNearestCity function finds the nearest unvisited city from the current city based on the distance matrix. The solveTSP function uses the Nearest Neighbor Algorithm to…

strategy for India to be world’s number 1 economy
Becoming the world’s number one economy is a complex and longterm goal that requires a comprehensive strategy. Here are some key strategies that India could consider to enhance its economic growth and competitiveness: Infrastructure Development: Invest heavily in infrastructure development, including transportation, energy, digital connectivity, and urbanization. This will attract both domestic and foreign investments,…

How do I mock an external dependency in Rust
In Rust, you can mock an external dependency using various techniques, depending on the nature of the dependency. Here are a couple of commonly used approaches: Dependency injection: This involves structuring your code in a way that allows you to inject different implementations of the dependency. By doing so, you can provide a mock implementation…

write hello world program in COBOL
Certainly! Here’s an example of a “Hello, World!” program written in COBOL: IDENTIFICATION DIVISION. PROGRAMID. HELLOWORLD. AUTHOR. YOURNAME. PROCEDURE DIVISION. DISPLAY ‘Hello, World!’. STOP RUN. In COBOL, the program structure is divided into various divisions. The IDENTIFICATION DIVISION specifies the program name and the author’s name. The PROCEDURE DIVISION contains the actual logic of the…

Print all subarrays with 0 sum
Given an array of integers, it is often required to find all subarrays 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…

Check if subarray with 0 sum is exists or not
Given an array of integers, it is often required to check if there exists a subarray with a sum equal to 0. This problem can be solved using two approaches – brute force and hashing. Approach 1: Brute Force The brute force approach involves checking every possible subarray in the given array to see if…

n smallest element in an array
Finding the X smallest elements in an array is a common problem in computer science and data analysis. The algorithm for finding the X smallest elements in an array can be implemented in various ways, but we will explore two popular approaches: sorting and using a priority queue. Approach 1: Sorting One of the simplest…
