900. Front number (course 7)
Title description
What if you know an integer a and want to output the N numbers before a?
Input format
Two positive integers in a row: a and N, in the range [1,10000].
Output format
N integers in a row:……a-2 a-1
Input/output example 1
enter:
10 5
Output:
5 6 7 8 9
st = input()
a = st.split()[0]
N = st.split()[1]
a = int(a)
N = int(N)
list = []
for i in range(a-N,a):
print(i,end=' ')901. Odd Number (Lesson 7)
Title description
Given N, output an odd number between 1 and N.
Input format
One positive integer per line: N, the range is [1,10000].
Output format
Positive odd numbers within [1...N].
Input/output example 1
enter:
10
Output:
1 3 5 7 9
N = input()
N = int(N)
for i in range(0,N+1):
if(i%2==1):
print(i, end=' ')902.7 Multiples of 7 (Lesson 7)
Title description
Output the multiples of 7 among all 3 digits from small to large.
Output format
A line of integers, separated by spaces.
Input/output example 1
enter:
Output:
105 112……
for i in range(100, 1000):
if i % 7 == 0:
print(i, end=' ')903. The Power of k (Lesson 7)
Title description
Input a positive integer k, output: k k*k k*k*k……, stop when it exceeds 8 digits.
Input format
In the first line, an integer k is in the range [2,15].
Output format
One line, multiple powers of k.
Input/output example 1
enter:
15
Output:
15 225 3375 50625 759375 11390625
st = input()
k = st.split()[0]
k = int(k)
k in range(2, 15)
result = k
while result < 100000000:
print(result, end=' ')
result *= k904. Arithmetic sequence (course 7)
Title description
A sequence of numbers, if the differences of two adjacent ones are equal, it is called an arithmetic sequence. For example: 2,5,8,11,14....
Now given the starting number a and the difference d, output the nth term.
Input format
Three positive integers in a row: a, d, and n, in the range [-100,100].
Output format
There are n integers in a row.
Input/output example 1
enter:
4 5 6
Output:
29
st = input()
a = st.split()[0]
d = st.split()[1]
n = st.split()[2]
a = int(a)
d = int(d)
n = int(n)
g = a + (n-1)*d
print(g)905. Double arithmetic sequence (course 7)
Title description
Find the Nth term of the following double arithmetic sequence.
1 2 4 7 11 16 22...
Input format
One positive integer per line: N, the range is [1,100].
Output format
1 integer.
Input/output example 1
enter:
4
Output:
7
st = input()
N = st.split()[0]
N = int(N)
N in range(1, 100)
a = 1
d = 0
i = 0
for i in range(N):
if i < N:
i = i+1
a += d
d += 1
print(a, end=" ")
