Question

Function: swapNext2BigNext2Small Input: 1. (1×N double) A Vector of numbers (N>=4) Output: 1. ( 1xN double) A Vector Function Description: - Given a 1XN vector where N>=4, return a new vector with the next to largest and next to smallest values swapped Note(s): - All values that are not being swapped should stay in the same location. - There will be no duplicate values in the vector Hint(s): - sort() may be useful - Use of a variable to hold a value may be helpful Examples:

Answer 1

Example 1:
Input: [3, 7, 2, 6, 1, 9]
Output: [3, 1, 2, 6, 7, 9]

Explanation:
In the input vector, the next to largest value is 7 and the next to smallest value is 2. Swapping these two values will result in the output vector.

Example 2:
Input: [5, 9, 12, 4, 8, 1, 6]
Output: [5, 1, 12, 4, 8, 9, 6]

Explanation:
In the input vector, the next to largest value is 9 and the next to smallest value is 4. Swapping these two values will result in the output vector.

Example 3:
Input: [1, 2, 3, 4, 5, 6, 7, 8]
Output: [1, 7, 3, 4, 5, 6, 2, 8]

Explanation:
In the input vector, the next to largest value is 7 and the next to smallest value is 2. Swapping these two values will result in the output vector.

Example 4:
Input: [10, 15, 20, 25, 30, 35, 40]
Output: [10, 35, 20, 25, 30, 15, 40]

Explanation:
In the input vector, the next to largest value is 35 and the next to smallest value is 15. Swapping these two values will result in the output vector.
