@Piyush-Pandey-2580479718941914 lots of mistakes removed the compilation error and commented where changed

#3

in have two doubts , what is diff between [ vector<pair<int,int>> g[n] and vector<pair<int,int>> g(n)

#4

vector<pair<int,int>> g[n] and vector<pair<int,int>> g(n)

#5

and why we have initialized vector in priority ueue

#6

@Piyush-Pandey-2580479718941914 its syntax of min heap priority queue int vector int greater int just refer gfg.
g[n] means array of vectors and g(n) means single vector

#7

see we are storing pair in heap ,greater is comparator but why we have initalized vector there
