Angry Professor 


A Discrete Mathematics professor has a class of  students. Frustrated with their lack of discipline, he decides to cancel class if fewer than  students are present when class starts.
Given the arrival time of each student, determine if the class is canceled.

Solution---
int main() {

   int t,n,k,a,r,j;
    scanf("%d",&t);
    int i;
    for(i=0;i<t;i++)
        {r=0;
        scanf("%d%d",&n,&k);
        for(j=0;j<n;j++){
       
           scanf("%d",&a);
            if(a<=0){
                r++;}
             
        }
   
        if(r>=k)
            printf("NO");
        else
            printf("YES");
        printf("\n");
    }
   
    return 0;
}

Cut the sticks

Cut the sticks     You are given   sticks, where the  length  of each stick is a positive integer. A  cut operation  is performed on the sticks such that all of them are reduced by the length of the smallest stick. ---Solution--- #include <cmath> #include <cstdio> #include <vector> #include <iostream> #include <algorithm> using namespace std; int compare (const void * a, const void * b) {   return ( *(int*)a - *(int*)b ); } int main() {     /* Enter your code here. Read input from STDIN. Print output to STDOUT */        int element,k;     cin>>element;     int array[element];     for(int i=0;i<element;i++)         {             cin>>array[i];     }      qsort (array, element, sizeof(int), compare);     int p=element;     for(int i=0;i...

Find Digits

Find Digits Given an integer,  , traverse its digits ( 1 , 2 ,..., n ) and determine how many digits evenly divide   (i.e.: count the number of times   divided by each digit  i  has a remainder of  ). Print the number of evenly divisible digits. Note:  Each digit is considered to be unique, so each occurrence of the same evenly divisible digit should be counted (i.e.: for  , the answer is  ). Solution--- #include<stdio.h> int main() {         int t,i,a,d,c,count,j;         scanf("%d",&t);         for(i=0;i<t;i++)         {       count=0;                 scanf("%d",&a);                 c=a;                 while(a!=0){               ...

Utopian Tree

Utopian Tree The Utopian Tree goes through  2  cycles of growth every year. Each spring, it  doubles  in height. Each summer, its height increases by  1  meter. Laura plants a Utopian Tree sapling with a height of  1  meter at the onset of spring. How tall will her tree be after   growth cycles? ----Solution-- import sys T = int(sys.stdin.readline()) for _ in range(T):     N = int(sys.stdin.readline())     height = 1              for i in range(N):         if i % 2 == 0:             height *= 2         else:             height += 1                  print(height)
