In mathematics, the Fibonacci numbers are the numbers in the following integer sequence, called the Fibonacci sequence, that is characterized by the fact that every number after the first two is the sum of the two preceding ones: Write a function named fib that takes in an input argument which should be integer number n, and then calculates the $n$th number in the Fibonacci sequence and outputs it on the screen. the input. Method 4: Using power of the matrix {{1, 1}, {1, 0}}This is another O(n) that relies on the fact that if we n times multiply the matrix M = {{1,1},{1,0}} to itself (in other words calculate power(M, n)), then we get the (n+1)th Fibonacci number as the element at row and column (0, 0) in the resultant matrix.The matrix representation gives the following closed expression for the Fibonacci numbers: Time Complexity: O(n)Auxiliary Space: O(1), Method 5: (Optimized Method 4)Method 4 can be optimized to work in O(Logn) time complexity.
