HackerEarth Milly and Chocolates IV problem solution YASH PAL, 31 July 202416 February 2026 In this HackerEarth Milly and Chocolates IV problem solution, Milly loves to eat chocolates. She has N different chocolates. She needs to choose only one of them. At the moment, ith chocolate already has Pi pieces. The jth piece of the ith chocolate requires Tij seconds to eat. Milly knows that she will take K seconds to break one piece from any chocolate and wait for M seconds after eating any piece. Your task is to help her in selecting chocolate that she will eat completely in the minimum possible time (including the waiting time).
