3003. Maximize the Number of Partitions After Operations

You are given a string s and an integer k. First, you are allowed to change at most one index in s to another lowercase English letter. After that, do the following partitioning operation until s is empty: Choose the longest prefix of s containing at most k distinct characters. Delete the prefix from s and increase the number of partitions by one. The remaining characters (if any) in s maintain their initial order. Return an integer denoting the maximum number of resulting partitions after the operations by optimally choosing at most one index to change.
/**
 * Calculates the maximum number of partitions after performing operations
 * that allow up to `k` distinct characters per partition.
 *
 * @param {string} s - Input string consisting of lowercase letters.
 * @param {number} k - Maximum number of distinct characters allowed per partition.
 * @return {number} - Maximum number of partitions achievable.
 */
var maxPartitionsAfterOperations = function(s, k) {
    const n = s.length;

    // L[i] stores [leftPartitions, leftMask, leftCount] for p

2598. Smallest Missing Non-negative Integer After Operations

You are given a 0-indexed integer array nums and an integer value. In one operation, you can add or subtract value from any element of nums. For example, if nums = [1,2,3] and value = 2, you can choose to subtract value from nums[0] to make nums = [-1,2,3]. The MEX (minimum excluded) of an array is the smallest missing non-negative integer in it. For example, the MEX of [-1,2,3] is 0 while the MEX of [1,0,3] is 2. Return the maximum MEX of nums after applying the mentioned operation any number of times.
/**
 * @param {number[]} nums
 * @param {number} value
 * @return {number}
 */
var findSmallestInteger = function(nums, value) {
    // Step 1: Create a frequency map to count how many times each remainder appears
    const freq = new Map();

    for (let num of nums) {
        // Normalize the remainder to always be non-negative
        let mod = ((num % value) + value) % value;

        // Count how many times each remainder appears
        freq.set(mod, (freq.get(mod) || 0) + 1);

Incorporating an Adaptive Interaction Strategy (AIS) to enhance interpretability. Providing a scalable and efficient computational framework for educational research. ✨ Key Features 🧠 Multimodal Data Fusion: Combines audio, visual, and contextual metadata to represent interaction dynamics. πŸ•’ Temporal & Hierarchical Modeling: Leverages RNN and attention-based mechanisms to capture both short- and long-term dependencies. 🌐 Adaptive Interaction Strategy (AIS): Introduces dynamic-static fusion through cross-attention and domain-specific constraints. πŸ“Š Strong Performance: Outperforms baseline models like ResNet, ViT, and I3D on multiple benchmark datasets. ⚑ Scalable & Efficient: Designed for real-world preschool environments with lightweight components. 🧱 Model Architecture The ChildLangNet architecture consists of three main components: Multimodal Encoder Extracts and fuses audio, visual, and contextual signals. Implements weak/strong augmentations, backbone encoders, and teacher-student EMA mechanisms. (See Figure 2 in the paper for a schematic view.) Graphical Propagation Layer Uses RNN with attention to model temporal dependencies. Aggregates segment-level representations hierarchically. Adaptive Interaction Strategy (AIS) Integrates static and dynamic feature streams via Neighborhood Cross Attention (NCA) and Dynamic-Static Interaction (DSI).
