Getting maximum elements in Julia - maximum() and maximum!() Methods

# Julia program to illustrate 
# the use of maximum() method

# Getting maximum elements in different scenarios

# In the below scenario, length function 
# and a list of elements are used as 
# parameter. Here the length of string with 
# maximum alphabets will be returned
println(maximum(length, ["GFG", "Geeks", "GeeksforGeeks"]))

# In the below scenario, a list of 
# elements are shown and maximum elements are 
# returned as output
println(maximum([5, 10, 15, 20]))

# Getting the maximum value of an array
# over the given dimensions
A = [5 10; 15 20];
println(maximum(A, dims = 1))
println(maximum(A, dims = 2))

# Julia program to illustrate 
# the use of maximum !() method

# Getting the maximum value of the
# specified array over the specified
# singleton dimensions.
A = [5 10; 15 20];
println(maximum !([1; 1], A))
println(maximum !([1 1], A))
