convert this code from TypeScript to Go:

const result: [number, number] = [0, 0]; // [depth, value]

In Go, we don't have built-in support for tuples or nullables in the same way as TypeScript, so I've used a pointer to an array (`*[2]int`) to mimic the `[number, number]` array in TypeScript.

Given an integer `n`, return `true` _if it is possible to represent_ `n` _as the sum of distinct powers of three._ Otherwise, return `false`.
An integer `y` is a power of three if there exists an integer `x` such that `y == 3x`.

The algorithm uses a simple approach by iteratively dividing the given number `n` by 3 (the base of the powers of three). During the division process, it checks if any of the remainders of division is 2. If it finds a remainder of 2 at any stage, it immediately returns `false` since having a 2 in the b... | First, I need to check if a given integer n can be represented as the sum of distinct powers of three. Powers of three are like 3^0 = 1, 3^1 = 3, 3^2 = 9, 3^3 = 27, and so on. They must be distinct, meaning no repeating the same power.
From the examples, 12 is 3^1 + 3^2 = 3 + 9, and 91 is 3^0 + 3^2 + 3^4 = 1 + 9 + 81.... | ```csharp

n = n / 3;

It initializes a variable `xor_result` to 0, then loops from 0 to n-1, and in each iteration, it XORs the current `xor_result` with the value of `start + 2 * i`. Finally, it returns the `xor_result`.

We iterate through the given string `s`. As we iterate, we maintain a frequency map `freq` of each character seen so far. At each step, we check if the size of `freq` is less than or equal to k. If it is, we update the result with the maximum frequency seen so far.

This algorithm iterates through the input array `chars`, for each character, it counts the number of consecutive occurrences (using `count` variable) of that character.
