Complexity Analysis
Generate the Fibonacci sequence up to
k
and store it in a list.
Initialize a counter to keep track of the number of Fibonacci numbers used.
Iterate through the Fibonacci sequence in reverse order.
For each Fibonacci number, check if it can be subtracted from
k
without making
k
negative.
If it can be subtracted, reduce
k
by the Fibonacci number and increment the counter.
Repeat steps 3-5 until
k
becomes zero.
Return the counter as the result.
