int findConsistentLogsconst std::vector& userEvent
int n userEvent.size;
Step : Calculate the minimum frequency in the entire array
std::unorderedmap freq;
for int user : userEvent
frequser;
int minfreq INTMAX;
for const auto& entry : freq
minfreq std::minminfreq, entry.second;
Step : Use sliding window to find the longest consistent subarray
int maxlength ;
std::unorderedmap windowfreq;
int left ;
for int right ; right n; right
windowfrequserEventright;
Check if the current window is consistent
while std::maxelementwindowfreq.begin windowfreq.end
const std::pair& a const std::pair& b return asecond bsecond; second minfreq
windowfrequserEventleft;
if windowfrequserEventleft
windowfreq.eraseuserEventleft;
left ;
Update the maximum length of consistent subarray
maxlength std::maxmaxlength, right left ;
return maxlength;
int main
std::vector userEvent ;
std::cout findConsistentLogsuserEvent std::endl; Output:
return ;
