@dips123deepali_c25f140838182212,
here pair<int,pair<int,int>> current is used (this is the custom class thing here)
it has 3 values first value can be accessed by current.first
2nd value by current.second.first
3rd value by current.second.second

to know about pair u can check this : https://www.educba.com/c-plus-plus-pair/

.second.second
