Problem 1: Closest Numbers
Description: Given an array of distinct integers, determine the minimum absolute difference between any two elements. Then, print all element pairs with that difference in ascending order.
Example: Input: numbers = [6, 2, 4, 10] Output: The minimum absolute difference is 2. The pairs with that difference are (2,4) and (4,6). The pairs should be ordered first by the first element and then by the second.
Function Description: Complete the function closestNumbers.
- Parameters:
int numbers[]: an array of integers
- Returns:
- None (the function prints the pairs directly)
Problem 2: Get Largest Number
Description: Given a string representing a number, you can swap two adjacent digits if they are of the same parity (both odd or both even). Find the largest number that can be created using any number of swaps.
Example: Input: num = "7596801" Steps:
- Swap 5 and 9 -> "7956801"
- Swap 7 and 9 -> "9756801"
- Swap 6 and 8 -> "9758601" Output: The largest value possible is "9758601".
Function Description: Complete the function getLargestNumber.
- Parameters:
string num: a string of digits
- Returns:
string: the largest number that can be created
