Why have we initialized starting index with -1
Insertion heap doubt
Hello @anika203a there are different appraoches to the question.
could you please share the code and tell where you are asking so that i can tell you .
Here in line 23
Hello @anika203a this i think we are doing because we are pushing the actual things we are pushing -1.
because when we will pop last element then if we want to perform operations on it then we can do this by taking -1 as before 0th index -1 is there .
it is simple.
