Welcome to the Week #295 of The Weekly Challenge.

Welcome back, Jorg Sommrey and thanks for sharing solutions to Week #290, Week #291, Week #292, Week #293 and Week #294. It is always pleasure to see contributions to past challenges.

Last week, I proposed an idea for Advent Calendar 2024 and requested for suggestions. I received few but none seems interested in video style advent calendar. I am still looking for new ideas for this year advent calendar. Please keep sharing your ideas to perlweeklychallenge@yahoo.com.

Task 1: Word Break

Submitted by: Mohammad Sajid Anwar

You are given a string, $str, and list of words, @words.

Write a script to return true or false whether the given string can be segmented into a space separated sequence of one or more words from the given list.

Example 1

Input: $str = 'weeklychallenge', @words = ("challenge", "weekly")
Output: true

Example 2

Input: $str = "perlrakuperl", @words = ("raku", "perl")
Output: true

Example 3

Input: $str = "sonsanddaughters", @words = ("sons", "sand", "daughters")
Output: false

Task 2: Jump Game

Submitted by: Mohammad Sajid Anwar

You are given an array of integers, @ints.

Write a script to find the minimum number of jumps to reach the last element. $ints[$i] represents the maximum length of a forward jump from the index $i. In case last element is unreachable then return -1.

Example 1

Input: @ints = (2, 3, 1, 1, 4)
Output: 2

Jump 1 step from index 0 then 3 steps from index 1 to the last element.

Example 2

Input: @ints = (2, 3, 0, 4)
Output: 2

Example 3

Input: @ints = (2, 0, 0, 4)
Output: -1
