+## Problem
+
+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/`
