The 2 sum problem is a mathematical problem where you are given a list of numbers and a target sum, and you need to find two numbers in the list that add up to the target sum. One effective way to solve this problem is by using a hash table to store the numbers as you iterate through the list. This allows you to quickly check if the complement of the current number (the difference between the target sum and the current number) is already in the hash table, indicating a pair that adds up to the target sum.

How can the t(n)t(n-1)t(n-2) recurrence equation be solved effectively?
One effective way to solve the recurrence equation t(n) t(n-1) t(n-2) is by using the Fibonacci sequence formula. This formula involves finding the sum of the previous two terms to calculate the next term in the sequence. By applying this formula iteratively, you can efficiently determine the value of t(n) for any given n.

What is the relationship between the infinity norm and the 2 norm in a vector space, and how can one be less than the other?
In a vector space, the infinity norm and the 2 norm are different ways to measure the size of a vector. The infinity norm is the maximum absolute value of any component in the vector, while the 2 norm is the square root of the sum of the squares of all the components. The infinity norm can be less than the 2 norm when the vector has a few very large components that dominate the sum of squares in the 2 norm calculation.
