Caloric Burn Analysis

You are given 7 integers, each representing the calories burned on a day over one week. Your task is to count the number of days on which the calories burned were at least 500.

You can express this using the formula:

$$\text{count} = \sum_{i=1}^{7} [cal_i \ge 500]$$

where \([cal_i \ge 500]\) is 1 if the condition is true and 0 otherwise.
