 QUESTION:

Factorial

Basic Accuracy: 54.57% Submissions: 4751 Points: 1

Given a positive integer, N. Find the factorial of N.
 

Example 1:

Input:
N = 5
Output:
120
Explanation:
5*4*3*2*1 = 120

Example 2:

Input:
N = 4
Output:
24
Explanation:
4*3*2*1 = 24


Your Task:
You don't need to read input or print anything. Your task is to complete the function factorial() which takes an integer N as input parameters and returns an integer, the factorial of N.

 

ANSWER:

long long int factorial(int N){
     long long int result=1;
     for(int i=1;i<=N;i++)
     {
         result*=i;
     }
     return result;
}

  Closest Number Given non-zero two integers N and M . The problem is to find the number closest to N and divisible by M . If there are more than one such number, then output the one having maximum absolute value .   Example 1: Input: N = 13 , M = 4 Output: 12 Explanation: 12 is the Closest Number to 13 which is divisible by 4. Example 2: Input: N = -15 , M = 6 Output: -18 Explanation: -12 and -18 are both similarly close to -15 and divisible by 6. but -18 has the maximum absolute value. So, Output is -18   ANSWER:   int closestNumber(int n , int m) { int q = n / ...

QUESTION: Consider a sample space S consisting of all perfect squares starting from 1, 4, 9 and so on. You are given a number N , you have to output the number of integers less than N in the sample space S. Example 1: Input : N = 9 Output: 2 Explanation: 1 and 4 are the only Perfect Squares less than 9. So, the Output is 2. Example 2: Input : N = 3 Output: 1 Explanation: 1 is the only Perfect Square less than 3. So, the Output is 1.   ANSWER:   int countSquares(int N) { int c=0; for(int i=1;i*i<N;i++) { c=c+1; } return c; }
