\n Blu-ray discs are media that can store large amounts of data, including movies, music, and data files.
\n Recently, a company wants to develop an algorithm to efficiently store data on Blu-ray discs.
\n Accordingly, each Blu-ray disc has a specific capacity, and multiple files need to be stored on this disc.
\n Given the sizes of the data to be stored and the maximum capacity of each disc, the problem is to determine the minimum number of discs required.\n <\/p>\n
\n The first line contains an integer array including the number of data files \n Output the minimum number of discs.\n <\/p>\n \n To solve this problem, the following approach is needed:\n <\/p>\n \n Below is the code written in Kotlin:\n <\/p>\n \n – The \n This problem requires an overall understanding of efficient disc management and storage space utilization. \n – When the number of Blu-ray discs is fixed, explore ways to optimize the file placement. <\/body><\/p>\n","protected":false},"excerpt":{"rendered":"N<\/code> (1 \u2264 N \u2264 1000) and the size of each file S_i<\/code> (1 \u2264 S_i \u2264 10^6).

\nfun minNumberOfDisks(fileSizes: ListCode Explanation<\/h2>\n
minNumberOfDisks<\/code> function takes a list of file sizes and the disc capacity as input.
\n – After sorting the file sizes in descending order, it determines the disc to add each file.
\n – If the current disk usage exceeds the capacity, a new disc is added, and the file usage is reset to the current file.
\n – After processing all files, the total number of discs is returned.
\n – The main<\/code> function verifies the functionality through an example input.\n <\/p>\nConclusion<\/h2>\n
\n The problem of determining the minimum number of discs required to store all files can be applied in various fields.
\n Solving algorithmic problems and considering various situations during optimization can enhance programming skills.\n <\/p>\nAdditional Challenges<\/h2>\n
