What is the condition for a tree to be weight balanced. where a is factor and n is a node?(a) weight[n.left] >= a*weight[n] and weight[n.right] >= a*weight[n].(b) weight[n.left] >= a*weight[n.right] and weight[n.right] >= a*weight[n].(c) weight[n.left] >= a*weight[n.left] and weight[n.right] >= a*weight[n].(d) weight[n] is a non zeroMy question is taken from Weight Balanced Tree topic in section Binary Trees of Data Structures & Algorithms IThis question was addressed to me during an interview. |
