Understanding the Take K of Each Character From Left and Right Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given a string s consisting of the characters 'a', 'b', and 'c' and a non-negative integer k. Each minute, you may take either the leftmost character of s, or the rightmost character of s. Return the minimum number of minutes needed for you to take at least k of each character, or return -1 if it is not possible to take k of each character.

Get real-time assistance for Take K of Each Character From Left and Right problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
s = "aabaaaacaabc", k = 28Take three characters from the left of s. You now have two 'a' characters, and one 'b' character. Take five characters from the right of s. You now have four 'a' characters, two 'b' characters, and two 'c' characters. A total of 3 + 5 = 8 minutes is needed. It can be proven that 8 is the minimum number of minutes needed.
s = "a", k = 1-1It is not possible to take one 'b' or 'c' so return -1.
Constraints
1 <= s.length <= 105s consists of only the letters 'a', 'b', and 'c'.0 <= k <= s.lengthHow Interview Coder Helps with Leetcode Problems
