JAVA IN & Code. You are given an integer A. Let's define an infinite sequenceS(A) = A%P, A²%P, A³%P,..., where P = 108 +7 is a prime and % isthe modulo operator.Let's also define a decreasing sum D(S) as the sum of all elements of asequence S which are strictly smaller than all preceding elements of S. When S isa sequence of non-negative integers, the number of such elements is clearly finite.Find D(S(A)).Input• The first line of the input contains a single integer T denoting the number oftest cases. The description of T test cases follows.• The first and only line of each test case contains a single integer A.OutputFor each test case, print a single line containing one integer D(S(A)).InputOutput232100000006100000007

In a company, there are several branches. Let us consider a branch of that company having N employees, if the manager is allotted to that branch(s) then he is known to everyone else in that branch. Note that the property of "known to everyone" is unique to a manager. Your task is to find the manager in that branch. Input from the user in main ( ), the square matrix M where if an element of row i and column j is set to 1 it means that ith person knows jth person. You need to write a function managerId ( ) which returns the id of the manager if present or else returns -1. The function managerId ( ) takes two arguments - the square matrix of N *N and its size N. Call managerId ( ) from the main ( ) output the information about the manager. Assume all diagonal elements to be 1 (as everyone knows him/herself) and there is at most one manager in the company.
1: Given a fixed integer B (B ≥ 2), we demonstrate that any integer N (N ≥ 0) can bewritten in a unique way in the form of the sum of p+1 terms as follows:N = a0 + a1×B + a2×B2 + … + ap×Bpwhere all ai, for 0 ≤ i ≤ p, are integer such that 0 ≤ ai ≤ B-1.The notation apap-1…a0 is called the representation of N in base B. Notice that a0 is theremainder of the Euclidean division of N by B. If Q is the quotient, a1 is the remainder of theEuclidean division of Q by B, etc.1. Write an algorithm that generates the representation of N in base B. 22. Compute the time complexity of your algorithm.
Q3 In a company, there are several branches. Let us consider a branch of that company having N employees, if the manager is allotted to that branch(s) then he is known to everyone else in that branch. Note that the property of "known to everyone" is unique to a manager. Your task is to find the manager in that branch. Input from the user in main (), the square matrix M where if an element of row i and column j is set to 1 it means that ith person knows jth person. You need to write a function managerId () which returns the id of the manager if present or else returns -1. The function managerId () takes two arguments - the square matrix of N *N and its size N. Call managerId () from the main () output the information about the manager. Assume all diagonal elements to be 1 (as everyone knows him/herself) and there is at most one manager in the company. Example: No of persons N = 3 Input matrix: 0 1 1 1 0 1 Output: manager is person 3 1 0 1
For this question, you will be required to use the binary search to find the root of some function f(x)f(x) on the domain x∈[a,b]x∈[a,b] by continuously bisecting the domain. In our case, the root of the function can be defined as the x-values where the function will return 0, i.e. f(x)=0f(x)=0 For example, for the function: f(x)=sin2(x)x2−2f(x)=sin2(x)x2−2 on the domain [0,2][0,2], the root can be found at x≈1.43x≈1.43 Constraints Stopping criteria: ∣∣f(root)∣∣<0.0001|f(root)|<0.0001 or you reach a maximum of 1000 iterations.
