How to use comparator in map?
Problem in map sorting
Please refer to this link.
I have read this article but cannot understand this. In map there are key and value pair. But in this comparator they compare two string a and b. I cannot understand what is this, key or value? I just make a comparator for map which is sorted based on descending order of value and if value is same then ascending order of key. Thank you
It is the key value.
Please refer to this link as well.
Also you could traverse the map and store the required values in a vector of pairs as {value,key}
Then sort the vector.
Thank you. But sir can you please tell me how to use comparator which is sorted based on descending order of value and if value is same then ascending order of key
Actually I don’t think a comparator of that type can be defined or not. And we rarely use comparators for maps.
