Sorting of an array of numbers

• If an array containing number is sorted using sort function it takes every value in the array as a string so 12 will be placed before 2. 
• Therefore, to consider the values as a number, spaceship operator() is used instead of cmp in the sort function. 
• This operator considers its operands as a number and sorts the data as a number.

# Initializing an array

@n = (12, 44, 2, 5, 25, 7, 96, 1);

  

# Printing Original Array

print "Original Array: @n\n";

  

# Sorting numbers with use of

# spaceship operator

@x = sort { $a <=> $b } @n;

  

# Printing sorted array

print "Array after Sorting: @x";




Output:

Original Array: 12 44 2 5 25 7 96 1
Array after Sorting: 1 2 5 7 12 25 44 96
