why my code fail in other test casees except 1

hello @Pranav7g
u need to print ur vector instead of map, by sorting it on the basis of last occurence.
refer this->
TLE in Testcase 5 in your code
use unordered map in place of map
and i can’t understand how compare function work
map is storing the last occurence of number right?
bool compare(int a,int b)
{
return m[a]<m[b]; //we sort the vector in acc. to the its value of the map,in inc. order
}
this comparator is just ordering elements in ascending order of their last occurence.
ooook thnks
