*my understanding* : by using this technique of frequency counting in an array for each element bounded , by nature this array inheretly sorted, u can use this array for additional stuff like for finding >= , <= for counting no of elements , u may additionally use suffixSumCount,PrefixSumCount. The pattern used in this solution is commonly referred to as the Counting Sort Pattern or Frequency Array Pattern. It is a specialized technique that leverages the bounded range of input values to achieve efficient computation. Here's a breakdown of the pattern: Key Characteristics of the Pattern Frequency Count: A frequency array (or histogram) is used to store the occurrences of each value in the input array. Cumulative Calculation: Cumulative sums of frequencies are computed to derive meaningful insights (like "how many elements are greater than or equal to 𝑥 Bounded Input: This pattern is efficient when the range of input values is small or can be bounded (e.g., 0 to 1000). Efficient Traversal: The traversal of the frequency array allows for O(1)-like operations over the input's range. Applications of the Pattern Problems involving rank-based queries or threshold comparisons: Counting elements ≥x,≤x, or within a specific range. Algorithms like Counting Sort for sorting integers in O(n)
