I want you to write a Java program to find the best time period.

There will be input data:

$57$

$-1-2-32-710-10$

The output is $10($I don't understand why it's $10)$

$5$ is the maximum sum of consecutive elements.

$7$ is the total number of elements in the array.

Input data:

$35$

$-124-15$

The output is $8($because the sum of the three consecutive elements is the highest, which is $4-15=8)$

Input data:

$210$

$-1-25401-8-18-5$

The output is $9($because the sum of the three consecutive elements is the highest, which is $54=9)$

I don't understand why the output for the first example is $10.$
