rollback() [1/2]

void rollback	(	array_type &	a,
		Time	from,
		Time	to,
		Size	steps
	)

solves the problem between the given times.

Warning:

being this a rollback, from must be a later time than to.

rollback() [2/2]

void rollback	(	array_type &	a,
		Time	from,
		Time	to,
		Size	steps,
		const condition_type &	condition
	)

solves the problem between the given times, applying a condition at every step.

Warning:

being this a rollback, from must be a later time than to.
