What does it mean when an algorithm checks for negative integers in a list?

When an algorithm checks for negative integers in a list, it is specifically confirming whether at least one negative integer is present within that list. This involves scanning through the elements to identify any values that are less than zero, which are defined as negative integers. The focus here is exclusively on detecting their existence, rather than performing actions related to counting all integers, validating positive integers, or assessing the integrity of the dataset in general. Thus, the core function of this check is to determine the presence of negative integers, making the choice that states it confirms the presence of at least one negative integer the most accurate representation of what that algorithm does.
