# Python: Find the value of n where n degrees of number 2 are written sequentially in a line without spaces

## Python Basic - 1: Exercise-19 with Solution

Write a Python program that finds the value of n when n degrees of number 2 are written sequentially on a line without spaces between them.

**Visual Presentation:**

**Sample Solution**:

**Python Code:**

```
# Define a function 'ndegrees' that calculates the highest power of a number 'n'
# such that the resulting number is found within a given input string 'num'.
def ndegrees(num):
ans = True # Initialize a boolean variable 'ans' to True.
n, tempn, i = 2, 2, 2 # Initialize variables 'n', 'tempn', and 'i'.
# Use a while loop to check conditions.
while ans:
# Check if the string representation of 'tempn' is found within 'num'.
if str(tempn) in num:
i += 1 # Increment 'i'.
tempn = pow(n, i) # Update 'tempn' with the next power of 'n'.
else:
ans = False # Set 'ans' to False if 'tempn' is not found in 'num'.
return i - 1 # Return the highest power (i-1).
# Test the 'ndegrees' function with different input strings and print the results.
print(ndegrees("2481632"))
print(ndegrees("248163264"))
```

Sample Output:

**Explanation: **

The above Python code defines a function "ndegrees()" that calculates the highest power of a number 'n' such that the resulting number is found within a given input string 'num'. Here's a brief explanation:

- Function Definition:
- def ndegrees(num):: Define a function named "ndegrees()" that takes a string num as input.
- Initialization:
- ans = True: Initialize a boolean variable 'ans' to 'True'.
- n, tempn, i = 2, 2, 2: Initialize variables 'n' (base number), 'tempn' (temporary result), and i (exponent) to 2.
- While Loop:
- while ans:: Enter a while loop that continues as long as 'ans' is 'True'.
- if str(tempn) in num:: Check if the string representation of 'tempn' is found within the input string 'num'.
- i += 1: Increment the exponent i.
- tempn = pow(n, i): Update 'tempn' with the next power of 'n'.
- else:: If 'tempn' is not found in 'num', set 'ans' to 'False' to exit the loop.
- Return Result:
- return i - 1: Return the highest exponent (i-1) that satisfies the condition.>
- Function Testing:
- print(ndegrees("2481632")): Test the function with the input string "2481632" and print the result.
- print(ndegrees("248163264")): Test the function with the input string "248163264" and print the result.
