# Ascending Order

While dealing with a set of numbers many a times a need arises to arrange the numbers in a certain order. The numbers can be arranged from the least valued number to the highest number or vice versa. When the least valued number comes first and the highest valued number comes last then it is known as ascending order. In an arrangement, when the highest valued number comes first and least valued number comes last then it is known as descending order. The set can have repetition of numbers also. If there are repeating numbers in the set then ascending order arrangement becomes non decreasing order and descending order arrangement becomes non increasing order.
