Problems
if01
Given three integers a, b, c, check the following statement “The number b is between a and c”.
Example 1:
Input: a=1
Output: 2
Example 2:
Input: a=-5
Output: -5
Constraints:
- -1018<=num<=1018
if02
If the number is positive, increase it to 1, else decrease it to 2.
Example 1:
Input: a=5
Output: 6
Example 2:
Input: a=-1
Output: -3
Constraints:
- -1018<=num<=1018
if03
If the number is positive, increase it to 1, else decrease it to 2. If it is 0, assign 10.
Example 1:
Input: a=-9
Output: -11
Example 2:
Input: a=3
Output: 4
Constraints:
- -1018<=num<=1018
if04
Find how many positive numbers there are in the given numbers.
Example 1:
Input: a=-2 b=4 c=1
Output: 2
Example 2:
Input: a=3 b=-3 c=-6
Output: 1
Constraints:
- -1018<=num<=1018
if05
Find how many negative numbers there are in the given numbers.
Example 1:
Input: a=-2 b=4 c=1
Output: 1
Example 2:
Input: a=3 b=-3 c=-6
Output: 2
Constraints:
- -1018<=num<=1018
if06
Find how many positive and how many negative numbers there are in the given numbers.
Example 1:
Input: a=-2 b=4 c=1
Output: "there are a lot of positive numbers"
Example 2:
Input: a=3 b=-3 c=-6
Output: "there are a lot of negative numbers"
Constraints:
- -1018<=num<=1018
if07
Given an integer a, check the following conditions: “positive odd number”, “positive even number”, “negative odd number”, “negative even number”, “the number is zero”
Example 1:
Input: a=57
Output: "positive odd number"
Example 2:
Input: a=-24
Output: "negative even number"
Constraints:
- -109<=num<=109
if08
Given an integer a, check the following conditions: “two-digit odd number”, “two-digit even number”, “three-digit odd number”, “three-digit even number”
Example 1:
Input: a=57
Output: "two-digit odd number"
Example 2:
Input: a=-242
Output: "three-digit even number"
Constraints:
- -103 < num < 10 3
if09
The two-digit integer is given.
Replace the digits of the number.
True if the resulting number is less than or equal to the old number, otherwise return False.
Example 1:
Input: a=57
Output: False
Example 2:
Input: a=21
Output: True
Constraints:
- -103 < num < 10 3
if10
Display the message according to the following temperature conditions given to you in Celsius:
Temp<0: "Freezing"
Temp 1-10: "Very Cold"
Temp 11-20: "Cold"
Temp 21-30: "Normal"
Temp 31-40: "Hot"
Temp >40: "Very Hot"
Example 1:
Input: a=21
Output: "Normal"
Example 2:
Input: a=-4
Output: "Freezing
Constraints:
- -103 < num < 10 3
