Doubt in codeof Trie

#1

Sir i ave two questions
1)why we use count here why it is used.
2) temp->children.count(ch).what this stmt. do.
3)

#2

  1. This count data member of Trie can be used to save the count of total words present in the Trie data Structure.

  2. temp->children.count(ch) here count is function for children which is a map, member of Node Structure, so for a map count is a function just like find(), where count() returns 1 if key is already present, return 0 when not present
