DSA - Two Pointer Approach - (In Progress)
The two-pointer approach is a powerful technique used to solve problems involving arrays or strings. Here are the key characteristics and criteria to identify if a problem can be effectively solved using the two-pointer approach: Characteristics of Two-Pointer Problems Sorted Input: The input array is sorted or can be easily sorted. Sorting often simplifies the problem and makes the two-pointer technique applicable. Finding Pairs or Subarrays: The problem involves finding pairs, triplets, or subarrays that satisfy specific conditions, such as a target sum....
