|
|
|
|
<ul>
|
|
<li>For transaction dates:
|
|
<ul>
|
|
<li>2024-07-01:
|
|
<ul>
|
|
<li>Sum of amounts for odd transactions: 75</li>
|
|
<li>Sum of amounts for even transactions: 150 + 200 = 350</li>
|
|
</ul>
|
|
</li>
|
|
<li>2024-07-02:
|
|
<ul>
|
|
<li>Sum of amounts for odd transactions: 0</li>
|
|
<li>Sum of amounts for even transactions: 300 + 50 = 350</li>
