SAN INSTALL

# SAN INSTALL

### BASE REQUIREMENTS

#### MAC OS

We're mostly following the dotsimulate install guide, python  ( via brew )

Install Brew

`/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"`

at the end of the install don't forget to follow the instruction to add brew to path: (use the one provided)
```bash
Run these commands in your terminal to add Homebrew to your PATH:
    echo >> /Users/o2d/.zprofile
    echo 'eval "$(/opt/homebrew/bin/brew she

Group Water Tight Geo

This snippet will group water tight geometry and colour them green as well as group open geometry and colour them red.

int shape_open = 0;

int npt = npoints(0);
for (int ptnum = 0; ptnum < npt; ptnum++)
{
    int pts[] = neighbours(0, ptnum);

    foreach (int pt; pts)
    {
        int hedge = pointhedge(0, ptnum, pt);
        int count = hedge_equivcount(0, hedge);

        if (count == 1)
        {
            shape_open = 1;
            break;
        }
    }
}

if (shape_open)
{
    @Cd = set(1,0,0);
    i@group_open=1;
}
else
{
    @Cd = set(0,1,0);
    i@group_closed=1;

2840. Check if Strings Can be Made Equal With Operations II

You are given two strings s1 and s2, both of length n, consisting of lowercase English letters. You can apply the following operation on any of the two strings any number of times: Choose any two indices i and j such that i < j and the difference j - i is even, then swap the two characters at those indices in the string. Return true if you can make the strings s1 and s2 equal, and false otherwise.

/**
 * @param {string} s1
 * @param {string} s2
 * @return {boolean}
 */
var checkStrings = function(s1, s2) {
    // We will separate characters by index parity:
    // even-indexed characters go into one bucket,
    // odd-indexed characters go into another.
    //
    // Because the allowed operation only lets us swap
    // characters whose indices differ by an EVEN number,
    // we can only rearrange characters *within* the same parity group.
    //
    // So the question becomes:
    //

2839. Check if Strings Can be Made Equal With Operations I

You are given two strings s1 and s2, both of length 4, consisting of lowercase English letters. You can apply the following operation on any of the two strings any number of times: Choose any two indices i and j such that j - i = 2, then swap the two characters at those indices in the string. Return true if you can make the strings s1 and s2 equal, and false otherwise.

/**
 * @param {string} s1
 * @param {string} s2
 * @return {boolean}
 */
var canBeEqual = function(s1, s2) {
    // --- Core idea ---
    // We are only allowed to swap:
    //   - index 0 ↔ 2   (even positions)
    //   - index 1 ↔ 3   (odd positions)
    //
    // This means characters can move *within* their parity group (even/odd),
    // but never cross between them.
    //
    // So the strings can be made equal if:
    //   1. The even-index characters match as a multiset
    //   2. The
