What is a code to minimum number of swaps required to minimize sum of absolute differences between adjacent array elements and the other steps required given the following:
Minimum number of swaps required to minimize sum of absolute differences between adjacent array elements | Function to find the minimum number of swaps required to sort the array in increasing order.
Stores the array elements with its index.
Sort the array in the increasing order.
Keeps the track of visited elements.
Stores the count of swaps required.
Traverse array elements.
If the element is already swapped or at correct position.
Find out the number of nodes in this cycle.
Update the value of j.
Move to the next element.
Increment cycle_size.
Update the ans by adding current cycle.
Function to find the minimum number of swaps required to sort the array in decreasing order.
Stores the array elements with its index.
Sort the array in the descending order.
Keeps track of visited elements.
Stores the count of resultant swap required.
