Minimum increments or decrements required to convert a sorted array into a power sequence | Function to find the minimum number of increments or decrements required to convert array into a power sequence.
Initialize the count to f ( X ) for X = 1.
Calculate the value of f ( X ) X ^ ( n - 1 ) <= f ( 1 ) + a [ n - 1 ].
Calculate F ( x ).
Check if X ^ ( n - 1 ) > f ( 1 ) + a [ n - 1 ].
Update ans to store the minimum of ans and F ( x ).
Return the minimum number of operations required.
