Program/Source Code:

The source code to demonstrate the assoc() method is given below. The given program is compiled and executed successfully.

# Ruby program to demonstrate the 
# assoc() method

arr1 = ["GODs","RAM","KRISHNA","SHIV"];
arr2 = ["COMPANY","HCL","TCS","WIPRO"];
arr3 = ["CITY", "DELHI", "MUMBAI", "AGRA"];

ArrayOfArray = [arr1,arr3,arr2];

X = ArrayOfArray.assoc("CITY")
Y = ArrayOfArray.assoc("GODs")
Z = ArrayOfArray.assoc("COMPANY")

print "#{X}\n";
print "#{Y}\n";
print "#{Z}\n";

Output:

["CITY", "DELHI", "MUMBAI", "AGRA"]
["GODs", "RAM", "KRISHNA", "SHIV"]
["COMPANY", "HCL", "TCS", "WIPRO"]

Explanation:

In the above program, we created 3 arrays arr1, arr2, arr3. Then we created an array of arrays. After that, we used the assoc() method to get the array based on the specified 1st element and printed the resulting arrays.
