Method Detail

getProgressionFinalElement

public static int getProgressionFinalElement(int start,
                                             int end,
                                             int increment)

Calculates the final element of a bounded arithmetic progression, i.e. the last element of the progression which is in the range from start to end in case of a positive increment, or from end to start in case of a negative increment.

No validation on passed parameters is performed. The given parameters should satisfy the condition: either increment > 0 and start <= end, or increment < 0 and start >= end.

Parameters:

start - first element of the progression

end - ending bound for the progression

increment - increment, or difference of successive elements in the progression

Returns:

the final element of the progression

getProgressionFinalElement

public static long getProgressionFinalElement(long start,
                                              long end,
                                              long increment)

Calculates the final element of a bounded arithmetic progression, i.e. the last element of the progression which is in the range from start to end in case of a positive increment, or from end to start in case of a negative increment.

No validation on passed parameters is performed. The given parameters should satisfy the condition: either increment > 0 and start <= end, or increment < 0 and start >= end.

Parameters:

start - first element of the progression

end - ending bound for the progression

increment - increment, or difference of successive elements in the progression

Returns:

the final element of the progression
