- - - Q1.Create a null vector (all zeros) of size 10 and set it in the variable called “Z”.
- - - Q2. Create a 1D array of numbers from 0 to 9 and set it in the variable called “arr”.
- - - Q3. Create a 3x3x3 array with random values and set it in the variable called “arr”.
- - - Q4. Create a 10x10 array with random values called “arr4”. Find its minimum and maximum values and set them in the variables called “min_val” and “max_val” respectively.
- - - Q5. First create a 1D array with numbers from 1 to 9 and then convert it into a 3x3 grid. Store the final answer in the variable called “grid”.
- - - Q6. Replace the maximum value in the given vector, “arr6”, with -1.
- - - Q7. Reverse the rows of the given 2D array, “arr7”.
- - - Q8. Subtract the mean of each row of the given 2D array, “arr8”, from the values in the array. Set the updated array in “transformed_arr8”.
