Name one conservation measure that will help in recharging the groundwater.
Show Hint
Solution and Explanation
One effective conservation measure to recharge groundwater is rainwater harvesting. This involves collecting rainwater from rooftops or other surfaces and storing it in tanks or underground reservoirs.
Step 2: Benefits of Rainwater Harvesting.
Rainwater harvesting helps in replenishing groundwater aquifers, especially during the monsoon season, ensuring a steady supply of water throughout the year and reducing the pressure on existing water sources.

- Object-Oriented Programming
- Write a program to accept a two-dimensional integer array of order \( 4 \times 5 \) as input from the user. Check if it is a Sparse Matrix or not. A matrix is considered to be a sparse, if the total number of zero elements is greater than the total number of non-zero elements. Print appropriate messages.
