So, i have an array of 30 elements, each of them can take the value from 0 to 1000
This part of the code is easy and i know how to write it. The complicated part is next: i need to write a program that returns the biggest value of the sum of the two adjacent elements.(a[i]+a[i+1])
a+a=7 # so it is what i'm searching for, 7 is bigger than 3, 5.
The thing is that i actually don't realize what methods/iterators/else? to use
.find_all doesn't seem to do what i need
.inject has the same trouble
so, what can you advice me?
thank you in advance

You can use the method each_cons(2) to get an enumerable containing two-element arrays for each 2 consecutive elements. So for example [1,2,3,4].each_cons(2) will give you the two-element arrays [1,2], [2,3], and [3,4]. From there you hopefully know how to continue.
