Write a program in Java to calculate pow(x,n) using recursion. The expected time complexity is O(log2N) where N is the power. You cannot use any extra space apart from the recursion call stack space..

Please help me solve this

Write a Java recursive method to print Fibonacci series of n terms. Fibonacci series starts with 0 and 1, and the sum of previous two numbers is the next number of the series. For instance, 0, 1, 1 (0 + 1), 2 (1 + 1), 3 (1 + 2), and so on. Sample input: 10Sample output:0 1 1 2 3 5 8 13 21 34

Write a java program to print the number from 1 to 100 without using loop, recursion, bitset.Think about arrays and do this with array in O(1) time complexity

Write a short recursive Java method that takes a character strings and outputs its reverse. For example, the reverse of 'pots&pans' would be 'snap&stop'.

Show a definition for a recursive Java method long powerOf2(int n) that returns the value of 2" (assume n is non-negative).

Write a recursive function in Java that accepts an integer as input and returns 1 + 1/2 + 3 + 1/4 + ...(n or 1/n). The answer is the sum of the odd integers from 1 to n plus the sum of the reciprocals of the even integers.

Write a recursive java code to compute the integer part of the base-two logarithm of n using only addition and integer division. Explain the time complexity of the code

Write a recursive method in java that sums all values between s and n inclusive     /*   assume s is less than or equal to n to start */    public static int sum(int s, int n)    {           }

Write a program that uses a recursive call to find the integer logb of a number. Where logb returns the integer log of a number in a designated base. For example, the integer base 10 log of 1234 is 3, and the integer base 2 log of 1234 is 10. This is a relatively easy calculation. You simply repeatedly divide the number by the base using integer division until the quotient is less than the base and count the number of completed divisions. 1234/10=123 (1) 123/10 12 (2) 12/10 = 1 (3) 1234/2= 617 (1) 617/2 = 308 (2) 308/2 = 154 (3) 154/2 = 77 (4) 77/2 = 38 (5) 38/2 = 19 (6) 19/2 = 9 (7) 9/2=4 (8) 4/2=2(9) 2/2 = 1 (10)
