Change Bits

Easy Accuracy: 72.48% Submissions: 1390 Points: 2

Given a number N, complete the following tasks,
Task 1. Generate a new number from N by changing the zeroes in the binary representation of N to 1.
Task  2. Find the difference between N and the newly generated number.

 

Example 1:

Input: N = 8 
Output: 7 15
Explanation:
There are 3 zeroes in binary representation
of 8. Changing them to 1 will give 15.
Difference between these two is 7.


Example 2:

Input: N = 6 
Output: 1 7
Explanation:
There is 1 zero in binary representation
of 6. Changing it to 1 will give 7.
Difference between these two is 1.

 

Your Task:
You don't need to read input or print anything. Your task is to complete the function changeBits() which takes an integer N as input parameter and returns a list of two integers containing the difference and the generated number respectively.



#code

tot=int(input())

for i in range(tot):

    num=int(input())

    l=[]

    l2=[]

    binn=bin(num)

    string=str(binn).replace("0b","")

    #print(type(string))

    for i in string:

        rep=i.replace("0","1")

        l.append(rep)

    res = int("".join(str(x) for x in l), 2)

    #print(res)

    num1=res-num

    l2.append(num1)

    l2.append(res)

    print(l2[0],l2[1])

Large Factorial of array

You are given an array   A   of integers of length   N . You need to calculate factorial of each number. The answer can be very large, so print it modulo   10 9  + 7 .   Example 1: Input: N = 5 A[] = {0, 1, 2, 3, 4} Output: 1 1 2 6 24 Explanation: Factorial of 0 is 1, factorial of 1 is 1, factorial of 2 is 2,  factorial of 3 is 6 and so on. Example 2: Input: N = 3 A[] = {5, 6, 3} Output: 120 720 6 Explanation: Factorial of 5 is 120, factorial of 6 is 720,  factorial of 3 is 6. Your Task: Complete the function  factorial()  which takes   list  a  and single integer  n , as input parameters and returns a list of factorials of the numbers in the list a.

Value equal to index value

Given an array   Arr   of   N   positive integers. Your task is to find the elements whose value is equal to that of its index value. Example 1: Input: N = 5 Arr[] = {15, 2, 45, 12, 7} Output: 2 Explanation: Only Arr[2] = 2 exists here. Example 2: Input: N = 1 Arr[] = {1} Output: 1 Explanation: Here Arr[1] = 1 exists. Your Task:   You don't need to read input or print anything. Your task is to complete the function  valueEqualToIndex()  which takes the array of integers  arr[]   and  n  as parameters and returns an array of indices where the given conditions are satified. When there is not such element exists then return an empty array of length 0. Expected Time Complexity:  O(N) Expected Auxiliary Space:  O(1) Note : There can be more than one element in the array which have same value as their index. You need to include every such element's index. Follows 1-based indexing of the array. Constraints: 1 ≤ N ≤ 10 5 1 ≤ Arr[i] ≤ 10 6

Largest Element in Array

  Given an array A[] of size n . The task is to find the largest element in it.   Example 1: Input: n = 5 A[] = {1, 8, 7, 56, 90} Output: 90 Explanation: The largest element of given array is 90.   Example 2: Input:   n = 7 A[] = {1, 2, 0, 3, 2, 4, 5} Output: 5 Explanation: The largest element of given array is 5.    def largest( arr, n):     return max(arr) #{ #  Driver Code Starts #Initial Template for Python 3 def main():     T = int(input())     while(T > 0):         n = int(input())         a = [int(x) for x in input().strip().split()]         print(largest(a, n))         T -= 1 if __name__ == "__main__":     main()
