1320. Minimum Distance to Type a Word Using Two Fingers

You have a keyboard layout as shown above in the X-Y plane, where each English uppercase letter is located at some coordinate. For example, the letter 'A' is located at coordinate (0, 0), the letter 'B' is located at coordinate (0, 1), the letter 'P' is located at coordinate (2, 3) and the letter 'Z' is located at coordinate (4, 1). Given the string word, return the minimum total distance to type such string using only two fingers. The distance between coordinates (x1, y1) and (x2, y2) is |x1 - x2| + |y1 - y2|. Note that the initial positions of your two fingers are considered free so do not count towards your total distance, also your two fingers do not have to start at the first letter or the first two letters.

/**
 * @param {string} word
 * @return {number}
 */
var minimumDistance = function(word) {
    // Keyboard coordinates for A–Z
    const pos = {};
    const layout = [
        "ABCDEF",
        "GHIJKL",
        "MNOPQR",
        "STUVWX",
        "YZ"
    ];
    
    for (let r = 0; r < layout.length; r++) {
        for (let c = 0; c < layout[r].length; c++) {
            pos[layout[r][c]] = [r, c];
        }
    }

    const dist = (a, b) => {
        const [x1, y1] = pos[a];

3741. Minimum Distance Between Three Equal Elements II

You are given an integer array nums. A tuple (i, j, k) of 3 distinct indices is good if nums[i] == nums[j] == nums[k]. The distance of a good tuple is abs(i - j) + abs(j - k) + abs(k - i), where abs(x) denotes the absolute value of x. Return an integer denoting the minimum possible distance of a good tuple. If no good tuples exist, return -1.

/**
 * @param {number[]} nums
 * @return {number}
 */
var minimumDistance = function(nums) {
    const lastTwo = new Map(); // value -> [prevPrev, prev]
    let ans = Infinity;

    for (let i = 0; i < nums.length; i++) {
        const v = nums[i];

        if (!lastTwo.has(v)) {
            lastTwo.set(v, [i]); // first occurrence
            continue;
        }

        const arr = lastTwo.get(v);

        if (arr.length === 1) {
            // second occurrence
            arr.push(i);
