A program to check if a string is a palindrome or not.

• A palindrome is a word, phrase, number, or other sequence of characters that reads the same forward and backward.

• To check if a string is a palindrome, we can compare the characters from the beginning and end of the string.

• If the characters match for all positions, the string is a palindrome.

Main function is the entry point of a program. It is used to execute the code in the program.

• Main function is required in every program written in C, C++, Java, etc.

• It is the first function to be executed when the program starts.

• It can take command line arguments.

• It returns an integer value to the operating system.

Static variables are variables that are associated with a class, not with an instance of the class.

• Static variables are declared using the 'static' keyword.

• They are initialized only once, at the start of the program.

• They can be accessed without creating an instance of the class.

• Static variables are shared among all instances of the class.

• Examples include a counter variable to keep track of the number of instances created, or a constant value that is used throughout the progra...read more

Use the quicksort algorithm to efficiently sort an array of strings.

• Implement the quicksort algorithm by selecting a pivot element and partitioning the array into two sub-arrays based on the pivot.

• Recursively apply the quicksort algorithm to the sub-arrays until the entire array is sorted.

• Example: ['apple', 'banana', 'cherry', 'date'] can be sorted using quicksort to ['apple', 'banana', 'cherry', 'date']

Lead scoring can be setup by defining criteria for assigning points to leads based on their behavior and demographics.

• Define criteria for assigning points based on lead behavior (e.g. website visits, email opens, form submissions)

• Assign points based on lead demographics (e.g. job title, company size, industry)

• Set thresholds for lead scores to determine when a lead is ready for sales follow-up

• Regularly review and adjust lead scoring criteria to ensure effectiveness
