Submitted by Nidhi, on January 12, 2022

Problem Solution:

In this program, we will use the assoc() method to get the array from an array of array-based on the specified first element.

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 1^st element and printed the resulting arrays.
