Solution
Here is a Python solution for Stefan's problem:
def find_pairs(arr, target):
# Create an empty dictionary
dic = {}
# Create an empty list to store pairs
pairs = []
# Iterate over each element in the array
for i in arr:
# Calculate the complement of the current element
complement = target - i
# If the complement is in the dictionary, a pair has been found
if complement in dic:
pairs

Single File Programming QuestionProblem StatementKrish is a computer science student who loves solving challenging problems. Recently, he came across an interesting problem related to arrays. The problem requires Krish to find all pairs of elements in a given array whose sum equals a specific target value. Write a program for Krish that takes an array of integers and a target sum as input. The program should print all pairs of elements from the array whose sum equals the target sum. If no such pairs are found, it should print "Not found".ExampleInput:5 // number of elements10 20 30 40 50 // elements60 // target sumOutput:10 5020 40Explanation: The pair with 60 as sum are 20 + 40 = 60 and 10 + 50 = 60.Input format :The first line consists of an integer N, representing the number of elements in the array.The second line consists of N space-separated integers, representing the elements of the array.The third line consists of an integer M, representing the target sum.Output format :For each pairs found, print two integers separated by a space, whose sum equals the target sum.If no such pairs are found, print "Not found".Refer to the sample output for the formatting specifications.Code constraints :In this scenario, the test cases will fall under the following constraints:2 ≤ N ≤ 251 ≤ Each element ≤ 1003 ≤ M ≤ 200Sample test cases :Input 1 :32 3 65Output 1 :2 3Input 2 :510 20 30 40 5060Output 2 :10 5020 40Input 3 :42 3 4 78Output 3 :Not foundInput 4 :310 6 410Output 4 :6 4

Two SumEasy53.1K1.8KCompaniesGiven an array of integers nums and an integer target, return indices of the two numbers such that they add up to target.You may assume that each input would have exactly one solution, and you may not use the same element twice.You can return the answer in any order. Example 1:Input: nums = [2,7,11,15], target = 9Output: [0,1]Explanation: Because nums[0] + nums[1] == 9, we return [0, 1].Example 2:Input: nums = [3,2,4], target = 6Output: [1,2]Example 3:Input: nums = [3,3], target = 6Output: [0,1] Constraints:2 <= nums.length <= 104
