Description
In a game, each character has an attack value and a defense value, represented by properties[i] = [attacki, defensei]. A character is considered weak if some other character surpasses it in both attack and defense simultaneously (strictly greater in both dimensions).
Return the total number of weak characters.
Example 1:
Input: properties = [[5,5],[6,3],[3,6]]
Output: 0
Explanation: No character has strictly greater attack and defense than the other.
Example 2:
Input: properties = [[2,2],[3,3]]
Output: 1
Explanation: The first character is weak because the second character has a strictly greater attack and defense.
Example 3:
Input: properties = [[1,5],[10,4],[4,3]]
Output: 1
Explanation: The third character is weak because the second character has a strictly greater attack and defense.
