While Loop: Sum Calculation

Easy

Problem Description

while loop: Sum Calculation

In this problem, you will create a program that uses a while loop to accumulate the sum of integers from 1 to a specified maximum value and displays the result to standard output.

Learning Objective: Implement accumulation processing with while loop

Calculate sum from 1 to specified number. Use while loop for cumulative addition.

Input

Line 1: Maximum value (integer, 1 or greater)

Output

Sum from 1 to [max]: [sum]
```java

## Examples

### Example 1: Sum from 1 to 5
Input:
```java
5
```java
Output:
```java
Sum from 1 to 5: 15
```java
1+2+3+4+5=15

### Example 2: Sum from 1 to 10
Input:
```java
10
```java
Output:
```java
Sum from 1 to 10: 55
```java
1+2+...+10=55

### Example 3: Sum from 1 to 1 (Boundary)
Input:
```java
1
```java
Output:
```java
Sum from 1 to 1: 1
