**Utopian Tree**

### Problem Statement :

The Utopian Tree goes through 2 cycles of growth every year. Each spring, it doubles in height. Each summer, its height increases by 1 meter. A Utopian Tree sapling with a height of 1 meter is planted at the onset of spring. How tall will the tree be after growth cycles? For example, if the number of growth cycles is n = 5, the calculations are as follows: Period Height 0 1 1 2 2 3 3 6 4 7 5 14 Function Description Complete the utopianTree function in the editor below. utopianTree has the following parameter(s): int n: the number of growth cycles to simulate Returns int: the height of the tree after the given number of cycles Input Format The first line contains an integer, t, the number of test cases. t subsequent lines each contain an integer, n, the number of cycles for that test case. Constraints 1 <= t <= 10 0 <= n <= 60

View Solution →## Tree: Huffman Decoding

Huffman coding assigns variable length codewords to fixed length input characters based on their frequencies. More frequent characters are assigned shorter codewords and less frequent characters are assigned longer codewords. All edges along the path to a character contain a code digit. If they are on the left side of the tree, they will be a 0 (zero). If on the right, they'll be a 1 (one). Only t
