## 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
