+## 📝 Instructions:
+
+1. Write a program which takes 2 digits, X,Y as input and generates a 2-dimensional array. The element value in the i-th row and j-th column of the array should be i*j.
 
-Write a program which takes 2 digits, X,Y as input and generates a 2-dimensional array. The element value in the i-th row and j-th column of the array should be i*j.
 Note: i=0,1.., X-1; j=0,1,¡­Y-1.
-Example
-Suppose the following inputs are given to the program:
-3,5
-Then, the output of the program should be:
-[[0, 0, 0, 0, 0], [0, 1, 2, 3, 4], [0, 2, 4, 6, 8]] 
-
-Hints:
-Note: In case of input data being supplied to the question, it should be assumed to be a console input in a comma-separated form.

+```text
+Q = Square root of (2 * c * d) / h
+```
+
+*Following are the fixed values of `c` and `h`:*
+
++ `c` is 50.
++ `h` is 30.
++ `d` would be the parameter of the function.
+
+## 📎 Example input:
+
+```py
+two_dimensional_array(3,5)
+```
+
+## 📎 Example output:
+
+```py
+[[0, 0, 0, 0, 0], [0, 1, 2, 3, 4], [0, 2, 4, 6, 8]]
+```
+
+## 💡 Hints:
+
++ If the output received is in decimal form, it should be rounded off to its nearest value (for example, if the output received is 26.0, it should be printed as 26).
+
++ Import the `math` module.
