Global JS refers to JavaScript variables or functions that are accessible from anywhere in the code.
Global JS variables are declared outside of any function and can be accessed from any part of the code.
Global JS functions are defined without being enclosed within another function and can be called from anywhere in the code.
Using global variables or functions can lead to potential conflicts and security risks.
Carry is generated when the sum of two digits is greater than 9.
Carry is a digit that is carried over to the next place value in the sum.
For example, in the sum 56 + 78, the carry generated is 1 (5+7=12, carry 1, 6+8+1=15).
Carry is important in addition of large numbers and in binary addition.
A program to find palindrome numbers in a given range.
Iterate through the given range of numbers
Convert each number to a string and check if it is equal to its reverse
If yes, add it to the list of palindrome numbers
Campaigns, Promotions, and Coupons are marketing strategies used to attract customers and increase sales.
Campaigns are strategic marketing efforts to promote a product or service over a specific period of time.
Promotions are temporary incentives offered to customers to encourage purchases, such as discounts or free gifts.
Coupons are vouchers that entitle the holder to a discount on a particular product or service.

The task is to find the total number of subsequences in which all elements are equal in an integer array.
Iterate through the array and count the frequency of each element.
For each element, calculate the number of subsequences with all elements equal using the formula (frequency * (frequency - 1) / 2).
Sum up the counts for all elements and return the result modulo 10^9 + 7.
