Question

Write python c∅de for the series,

1 2 1 3 4 3 5 6 5 7 8 7...N terms.
​

Answer 1

Answer:

Input: N = 4

Output: 2, 1, 4, 3

Explanation:

Nth Term = (N % 2 == 0) ? (N - 1) : (N + 1)

1st term = (1 % 2 == 0) ? (1 - 1) : (1 + 1)

= (1 + 1)

= 2

2nd term = (2 % 2 == 0) ? (2 - 1) : (2 + 1)

= (2 - 1)

= 1

3rd term = (3 % 2 == 0) ? (3 - 1) : (3 + 1)

= (3 + 1)

= 4

4th term = (4 % 2 == 0) ? (4 - 1) : (4 + 1)

= (4 - 1)

= 3

Therefore, Series = 2, 1, 4, 3

Input: N = 7

Output: 2, 1, 4, 3, 6, 5, 8

Answer 2

Answer:

hello friend

a very good morning to you.

Explanation:

Input: N = 4

Output: 2, 1, 4, 3

Explanation:

Nth Term = (N % 2 == 0) ? (N - 1) : (N + 1)

1st term = (1 % 2 == 0) ? (1 - 1) : (1 + 1)

= (1 + 1)

= 2

2nd term = (2 % 2 == 0) ? (2 - 1) : (2 + 1)

= (2 - 1)

= 1

3rd term = (3 % 2 == 0) ? (3 - 1) : (3 + 1)

= (3 + 1)

= 4

4th term = (4 % 2 == 0) ? (4 - 1) : (4 + 1)

= (4 - 1)

= 3

Therefore, Series = 2, 1, 4, 3

Input: N = 7

Output: 2, 1, 4, 3, 6, 5, 8
