ACPC10A - What’s Next
According to Wikipedia, an arithmetic progression (AP) is a sequence of numbers such that the difference of any two successive members of the sequence is a constant. For instance, the sequence 3, 5, 7, 9, 11, 13, . . . is an arithmetic progression with common difference 2. For this problem, we will limit ourselves to arithmetic progression whose common difference is a non-zero integer.
On the other hand, a geometric progression (GP) is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed non-zero number called the common ratio. For example, the sequence 2, 6, 18, 54, . . . is a geometric progression with common ratio 3. For this problem, we will limit ourselves to geometric progression whose common ratio is a non-zero integer.
Given three successive members of a sequence, you need to determine the type of the progression and the next successive member.
Your program will be tested on one or more test cases. Each case is specified on a single line with three integers (−10, 000 < a1 , a2 , a3 < 10, 000) where a1 , a2 , and a3 are distinct.
The last case is followed by a line with three zeros.
For each test case, you program must print a single line of the form:
where XX is either AP or GP depending if the given progression is an Arithmetic or Geometric Progression. v is the next member of the given sequence. All input cases are guaranteed to be either an arithmetic or geometric progressions.
4 7 10
2 6 18
0 0 0
its easy but be careful to add a space in the output between Ap and the next no. it will
AC in 4th go..!!
AC in one GO!!!
There is no need to check for -5,0,5 or division by zeroLast edit: 2017-09-06 19:54:26
Be careful about division by 0 and in the case of GP having one of the 2nd or 3rd number is zero
While loop slapped me in the face :) wrong end condition costed me WA
be careful for -5, 0, 5
it is not accepting could someone find mistakes http://ideone.com/ZNaxYd
AC in one GO.
AC in 2nd GO!!
