Given an unsorted array A[]. The task is to print all unique pairs in the unsorted array with equal sum. Note: Print the result in the format as shown in the below examples.

Examples:

Input: A[] = { 6, 4, 12, 10, 22, 54, 32, 42, 21, 11}
Output:
Pairs : ( 4, 12) ( 6, 10) have sum : 16
Pairs : ( 10, 22) ( 21, 11) have sum : 32
Pairs : ( 12, 21) ( 22, 11) have sum : 33
Pairs : ( 22, 21) ( 32, 11) have sum : 43
Pairs : ( 32, 21) ( 42, 11) have sum : 53
Pairs : ( 12, 42) ( 22, 32) have sum : 54
Pairs : ( 10, 54) ( 22, 42) have sum : 64

Input:A[]= { 4, 23, 65, 67, 24, 12, 86}
Output:
Pairs : ( 4, 86) ( 23, 67) have sum : 90

Solution

Solution in nordhealth_test/solution.py:51 (print_pairs_with_same_sum())

Tests for the inputs are defined it tests/test_solution.py

For package manager I am using poetry, so to activate venv:

poetry install
poetry env activate

Running

to run the solution:

chmod +x ./nordhealth_test/solution.py
./nordhealth_test/solution.py [path to input file]
- Example: ./nordhealth_test/solution.py ./inputs/input1.txt

To run the tests:

pytest tests/
