problem no 42:(array problem):return the count of the elements which are less than or equal to x.

-

 QUESTION:

Given an sorted array A of size N. Find number of elements which are less than or equal to given element X.

 

Example 1:

Input:
N = 6
A[] = {1, 2, 4, 5, 8, 10}
X = 9
Output:
5

 

Example 2:

Input:
N = 7
A[] = {1, 2, 2, 2, 5, 7, 9}
X = 2
Output:
4
 
 
ANSWER:
int countOfElements(int arr[], int n, int x) 
{
  int count=0;
  for(int i=0;i<n;i++)
  {
      if(arr[i]<=x)
      {
          count =count+1;
      }
  }
  return count;
  
}

  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; }
