Find minimum array element in Ruby

In this article, we will learn how to find minimum array element in Ruby. There are multiple ways to find minimum array element in Ruby. Let’s understand each of them with the help of example.

Example #1:

# min function on list
arr =[1, 2, 3, 4, 5].min
print arr
print "\n"


str1 = [1, 2, 3, 4, 5]
puts  str1.min
print "\n"

# min function on string
str = ["GFG", "G4G", "Sudo", "Geeks"]
print str.min

Output:

Example #2:

 arr.min
end

print min(1, 2, 3, 4, 5)
