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: Nis an integer within the range (-8,000..8,000)
