Python3 hackerRank exercise with solutions (Set 4)
1. Python If-Else
Given an integer, n, perform the following conditional actions:
- If is odd, print
Weird - If is even and in the inclusive range of to , print
Not Weird - If is even and in the inclusive range of to, print
Weird - If is even and greater than , print
Not Weird
Input format :
A single line containing an integer N. (i.e.N>0)
Output format :
Print weird if the number is weird. Else print Not weird
Sample input :
3
Sample output :
Weird
Code :
n=int(input())
if((n>20)&(n%2==0)):
print("Not weird")
else:
if(n%2==0):
print("Not weird")
if(n>2)&(n<5):
print("Weird")
elif(n<20)&(n>6):
2. Arithmetic Operators
The code reads two integers a and b from user and print three lines where,
- the first line contains the sum of two integers, a+b
- the second line contains the difference of two integers, a-b
- the third line contains the product of two integers, a*b
Input format :
The first line contains the integer a.
The second line contains the integers b.
Output format :
The first line contains the sum of two integers, a+b.
The second line contains the difference of two integers, a-b.
The third line contains the product of two integers, a*b.
Sample input :
3
2
Sample output :
5
1
6
Code :
a=int(input())
b=int(input())
#sum of integers
print(a+b)
#difference of integers
print(a-b)
#product of integers
print(a*b)
3. Division
The code reads two integers a and b from user and print two lines where,
- the first line contains the result of integer division, a//b
- the second line contains the result of float division, a/b
Input format :
The first line contains the integer a.
The second line contains the integers b.
Output format :
The first line contains the result of integer division, a//b
The second line contains the result of float division, a/b
Sample input :
4
3
Sample output :
1
1.33333333333
Code :
a=int(input())
b=int(input())#integer division
print(a//b)
#float division
print(a/b)
4. Loops
The code reads an integer n where, n>0. For the list of non-negative integers
that are less than n, print the square of the elements on separate lines.
Input format :
A single line containing an integer, n.
Output format :
Print n lines, one corresponding to each i.
Sample input :
5
Sample output :
0
1
4
9
16
Code :
n=int(input())
for i in range(0,n):
print(i*i)
5. Find the Runner-Up Score!
Given the participant's score sheet for you university sports day, you are
required to find the runner up score. You are given n scores. Store them in a
list and find the score of the runner-up.
Input format :
The first line contains an integer n. The second line contains an array of
integers
each separated by space.
Output format :
Print the runner-up score.
Sample input :
5
2 3 6 6 5
Sample output :
5
Code :
n=int(input())
#array input
arr = map(int, input().split())
arr=list(arr)
new = []
for i in arr:
if i not in new:
new.append(i)
new.sort()
print(new[-2])
