A1042. Shuffling Machine (20)

Description:

Shuffling is a procedure used to randomize a deck of playing cards.
Because standard shuffling techniques are seen as weak, and in order to
avoid “inside jobs” where employees collaborate with gamblers by
performing inadequate shuffles, many casinos employ automatic shuffling
machines
. Your task is to simulate a shuffling machine.

The machine shuffles a deck of 54 cards according to a given random
order and repeats for a given number of times. It is assumed that the
initial status of a card deck is in the following order:

S1, S2, …, S13, H1, H2, …, H13, C1, C2, …, C13, D1, D2, …, D13,
J1, J2

where “S” stands for “Spade”, “H” for “Heart”, “C” for “Club”, “D” for
“Diamond”, and “J” for “Joker”. A given order is a permutation of
distinct integers in [1, 54]. If the number at the i-th position is j,
it means to move the card from position i to position j. For example,
suppose we only have 5 cards: S3, H5, C1, D13 and J2. Given a shuffling
order {4, 2, 5, 3, 1}, the result will be: J2, H5, D13, S3, C1. If we
are to repeat the shuffling again, the result will be: C1, H5, S3, J2,
D13.

Input:

pat模拟习题集,轻易模拟习题集。Each input file contains one test case. For each case, the first line
contains a positive integer K (<= 20) which is the number of repeat
times. Then the next line contains the given order. All the numbers in a
line are separated by a space.

Output:

For each test case, print the shuffling results in one line. All the
cards are separated by a space, and there must be no extra space at the
end of the line.

A1046.Shortest Distance (20)

Description:

The task is really simple: given N exits on a highway which forms a
simple cycle, you are supposed to tell the shortest distance between any
pair of exits.

Input:

Each input file contains one test case. For each case, the first line
contains an integer N (in [3, 105]), followed by N integer
distances D1 D2 … DN, where
Di is the distance between the i-th and the (i+1)-st exits,
and DN is between the N-th and the 1st exits. All the numbers
in a line are separated by a space. The second line gives a positive
integer M (<=104), with M lines follow, each contains a
pair of exit numbers, provided that the exits are numbered from 1 to N.
It is guaranteed that the total round trip distance is no more than
107.

Output:

For each test case, print your results in M lines, each contains the
shortest distance between the corresponding given pair of exits.

A1009. Product of Polynomials (25)

Description:

This time, you are supposed to find A*B where A and B are two
polynomials.

Input:

Each input file contains one test case. Each case occupies 2 lines, and
each line contains the information of a polynomial: K N1
aN1 N2 aN2 … NK aNK, where K is the
number of nonzero terms in the polynomial, Ni and aNi (i=1,
2, …, K) are the exponents and coefficients, respectively. It is given
that 1 <= K <= 10, 0 <= NK < … < N2 < N1 <=1000.

Output:

For each test case you should output the product of A and B in one line,
with the same format as the input. Notice that there must be NO extra
space at the end of each line. Please be accurate up to 1 decimal place.

Sample Input:

2 1 2.4 0 3.2

Shuffling is a procedure used to randomize a deck of playing cards.
Because standard shuffling techniques are seen as weak, and in order to
avoid “inside jobs” where employees collaborate with gamblers by
performing inadequate shuffles, many casinos employ automatic
shuffling machines
. Your task is to simulate a shuffling machine.

The machine shuffles a deck of 54 cards according to a given random
order and repeats for a given number of times. It is assumed that the
initial status of a card deck is in the following order:

S1, S2, …, S13, H1, H2, …, H13, C1, C2, …, C13, D1, D2, …, D13,
J1, J2

where “S” stands for “Spade”, “H” for “Heart”, “C” for “Club”, “D” for
“Diamond”, and “J” for “Joker”. A given order is a permutation of
distinct integers in [1, 54]. If the number at the i-th position is j,
it means to move the card from position i to position j. For example,
suppose we only have 5 cards: S3, H5, C1, D13 and J2. Given a shuffling
order {4, 2, 5, 3, 1}, the result will be: J2, H5, D13, S3, C1. If we
are to repeat the shuffling again, the result will be: C1, H5, S3, J2,
D13.

Input Specification:

Each input file contains one test case. For each case, the first line
contains a positive integer K (<= 20) which is the number of repeat
times. Then the next line contains the given order. All the numbers in a
line are separated by a space.

Output Specification:

For each test case, print the shuffling results in one line. All the
cards are separated by a space, and there must be no extra space at the
end of the line.

Sample Input:

Sample Output:

S7 C11 C10 C12 S1 H7 H8 H9 D8 D9 S11 S12 S13 D10 D11 D12 S3 S4 S6 S10 H1 H2 C13 D2 D3 D4 H6 H3 D13 J1 J2 C1 C2 C3 C4 D1 S5 H5 H11 H12 C6 C7 C8 C9 S2 S8 S9 H10 D5 D6 D7 H4 H13 C5

Shuffling
is a procedure used to randomize a deck of playing cards. Because
standard shuffling techniques are seen as weak, and in order to avoid
“inside jobs” where employees collaborate with gamblers by performing
inadequate shuffles, many casinos employ automatic shuffling machines.
Your task is to simulate a shuffling machine.

The
machine shuffles a deck of 54 cards according to a given random order
and repeats for a given number of times. It is assumed that the initial
status of a card deck is in the following order:

S1,
S2, …, S13, H1, H2, …, H13, C1, C2, …, C13, D1, D2, …, D13, J1,
J2

S1,
S2, …, S13, H1, H2, …, H13, C1, C2, …, C13, D1, D2, …, D13, J1,
J2

where
“S” stands for “Spade”, “H” for “Heart”, “C” for “Club”, “D” for
“Diamond”, and “J” for “Joker”. A given order is a permutation of
distinct integers in [1, 54]. If the number at the i-th position is j,
it means to move the card from position i to position j. For example,
suppose we only have 5 cards: S3, H5, C1, D13 and J2. Given a shuffling
order {4, 2, 5, 3, 1}, the result will be: J2, H5, D13, S3, C1. If we
are to repeat the shuffling again, the result will be: C1, H5, S3, J2,
D13.

Input:

Input:

Each
input file contains one test case. For each case, the first line
contains an integer N (in [3, 105]), followed by N integer
distances D1 D2 … DN, where
Di is the distance between the i-th and the (i+1)-st exits,
and DN is between the N-th and the 1st exits. All the numbers
in a line are separated by a space. The second line gives a positive
integer M (<=104), with M lines follow, each contains a
pair of exit numbers, provided that the exits are numbered from 1 to N.
It is guaranteed that the total round trip distance is no more than
107.
