What is the maximum total number of nodes in a tree that
has N levels? Note that the root is level (zero)

• hey the right answer is 2^(n+1)-1 for example if the level is 2 from zero then max nodes used are 7 =2^(2+1)-1

• (2 pow n)-1,if root level is one and (2 pow n+1)-1, if root
  level is zero.

• 2^n
  max no. of nodes at level i is 2^(i-1)
  so here total levels are n+1

• n nodes bec level =hight +1
  
• 10 years agoHelpfull: Yes(0) No(0)
• nodes=2^n-1
  where n is no of nodes

• hey the right answer is 2^(n)-1 .
