HEADLINES

Welcome to the Week #302 of The Weekly Challenge.

Let us all welcome a new member, Andreas Mahnke, from Germany. Thanks for sharing your first contributions in Perl.

Two in a row, we received contributions in Perl and C from Ryan Thompson. There is bonus blog post too.

I would also like to thank, Bruno Ramos, a long time Team PWC member for the first contributions in Perl. I hope to see more in coming weeks.

We’ve now completed successfully another Advent Calendar, the 6th in a row. A big thanks to each and every contributors. It wouldn’t have possible without your consistent support and encouragement.

I am hoping your new year celebration is already started. I wish you all a very healthy and prosperous new year.

Task 1: Ones and Zeroes

Submitted by: Mohammad Sajid Anwar

You are given an array of binary strings, @str, and two integers, $x and $y.

Write a script to return the size of the largest subset of @str such that there are at most $x 0’s and $y 1’s in the subset.

A set m is a subset of n if all elements of m are also elements of n.

Example 1

Input: @str = ("10", "0001", "111001", "1", "0")
       $x = 5
       $y = 3
Output: 4

The largest subset with at most five 0's and three 1's:
("10", "0001", "1", "0")

Example 2

Input: @str = ("10", "1", "0")
       $x = 1
       $y = 1
Output: 2

The largest subset with at most one 0's and one 1's:
("1", "0")

Task 2: Step by Step

Submitted by: Mohammad Sajid Anwar

You are given an array of integers, @ints.

Write a script to find the minimum positive start value such that step by step sum is never less than one.

Example 1

Input: @ints = (-3, 2, -3, 4, 2)
Output: 5

For start value 5.
5 + (-3) = 2
2 + (+2) = 4
4 + (-3) = 1
1 + (+4) = 5
5 + (+2) = 7

Example 2

Input: @ints = (1, 2)
Output: 1

Example 3

Input: @ints = (1, -2, -3)
Output: 5

Last date to submit the solution 23:59 (UK Time) Sunday 5^th January 2025.
