Can Moderator A Remove Moderator B Based on Add Order

Problem: Determine if Moderator A Can Remove Moderator B Given the same moderator audit log log (same format as in the previous problem), implement a method to determine whether moderator A is allowed to remove moderator B. Rule: Use each moderator's first add timestamp as their join order Return true if A's first-add timestamp is earlier than B's first-add timestamp; otherwise return false If either A or B never appears in an add action (i.e., has no first-add time), return false I/O Input: log string log, and two strings A, B Output: boolean Example Log: mod2,add,mod1,100 mod3,add,mod2,101 mod2,remove,mod3,102 mod2,add,mod1,103 canRemove(log, "mod3", "mod2") => false canRemove(log, "mod2", "mod3") => true Example Input mod2,add,mod1,100 mod3,add,mod2,101 mod2,remove,mod3,102 mod2,add,mod1,103 mod2 mod3 Output true
