Question

Q2- Write a function solution that, given an integer N, returns the maximum possible value obtained by inserting one '5' digit inside the decimal representation of integer N.

Examples:

1. Given N = 268, the function should return 5268.

2. Given N = 670, the function should return 6750.

3. Given N = 0, the function should return 50.

4. Given N = −999, the function should return −5999.

Assume that:

N is an integer within the range [−8,000..8,000].

Answer 1

According to the problem statement,

With all due respect, you haven't mentioned any particular programming language to write a function for this problem statement.

So, I have coded the function using the PYTHON programming language.

Code Snippet:

Function Code in Text Format:

def MaximumPossibleValue(self, N):

        if N >= 0:
            value = str(N)
            for i in range(len(value)):
                if '5' > value[i]:
                    return int(value[:i] + '5' + value[i:])
          
        else:
            value = str(N)
            for i in range(1, len(value)):
                if '5' < value[i]:
                    return int(value[:i] + '5' + value[i:])
          
        return int(value + '5')

Explanation

for example if you take 670,

maximum possible value is 6750

it will start looping from 0th index

5 is not greater than 6 so it will move to the next index which 1

5 is not greater than 7 so it will move to the next index which 2

5 is greater than 0 so it will print 67 and append 5 to index number 2 and then it will append the remaining string 0

So the final output is 6750

I hope the function snippet and output explanation will help you out!

Thank you!
