The 2 sum problem involves finding two numbers in an array that add up to a specific target sum.

• Use a hash map to store the difference between the target sum and each element in the array.

• Iterate through the array and check if the current element's complement exists in the hash map.

• Return the indices of the two numbers that add up to the target sum.

To solve a sum problem, you need to add the numbers together.

• Identify the numbers that need to be added together.

• Add the numbers using the appropriate mathematical operation.

• Check your answer for accuracy.

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

• Check if the given string is equal to its reverse

• Ignore spaces and punctuation when checking for palindromes

• Convert the string to lowercase before checking for palindrome

Magical number can be solved by identifying the pattern or rule that governs the numbers and applying it to find the next number in the sequence.

• Identify the pattern or rule in the given numbers

• Apply the pattern to find the next number in the sequence

• Examples: Fibonacci sequence, prime numbers, arithmetic progression

To solve array subset problem, use a combination of iteration and comparison to find all possible subsets.

• Iterate through the array and generate all possible subsets using bitwise manipulation or recursion.

• Compare each subset with the target subset to check for a match.

• Return true if a matching subset is found, otherwise return false.
