Problem Statement

Write a PyTorch program to:

1. Create a 1-dimensional tensor of size 10, initialized with integer values from 1 to 10 (inclusive)

2. Reshape this tensor to a 2-dimensional tensor of size 2x5

3. Compute and print the mean and standard deviation of the reshaped tensor

4. Convert the reshaped tensor to a Python list and print it

---

Example Output

Mean of reshaped tensor: 14.5
Standard deviation of reshaped tensor: 3.0276503562927246
[[10.0, 11.0, 12.0, 13.0, 14.0], [15.0, 16.0, 17.0, 18.0, 19.0]]

Constraints

• Use PyTorch tensors (not NumPy)
• Tensor must be reshaped to exactly 2x5
• Use appropriate PyTorch functions for mean and std
