Crop cultivation strategy If a crop is grown for once, the fertility of the soil reduces by 30. After cultivation, if the land is left free for one month, the fertility increases by a factor of 2. If the fertility becomes 0, the crop cannot be grown futher. Write a program to get the initial fertility and get the number of months the land is left free after every cultivation and find the number of times the crops are successfully grown, before the fertility becomes 0. Note 1:  If the fertility becomes 0 in the middle of the growth of crop, the crop stops growing. Note 2:  Stop getting the input if the fertility becomes 0. Input Format: First input is an integer that corresponds to the initial fertility of the soil. Next inputs are number of months the land is left free after every cultivation. Output Format: Number of times the crops are grown successfully. Sample Input: 35 3 1 Sample Output: 2 Explanation : 35->after first cultivation fertility becom...

Plants under shade There are certain plants that needs to be grown under the shade of huge trees and the dead leaves from the trees become the natural manure for the plants. So willow trees are planted throughout the village at certain positions. The position(distance from the first tree) follows the following series 0 6 10 17 22 30 36....

Fencing the ground Two non-overlapping fields need to be fenced together to guard from cattle. The fence is always a single rectangle, which cover the two fields exactly. Given the left bottom coordinate, length and width of the two fields, write a program to find dimension of the fence. Print “Invalid Input” if the fields overlap.   Input Format: The 1 st  line of the input consists of 4 integers separated by a space that correspond to x, y, l and w of the first rectangle. The 2 nd  line of the input consists of 4 integers separated by a space that correspond to x, y, l and w of the second rectangle. Output Format: Output consists of 4 integers that correspond to x, y, l and w of the Union rectangle. Sample Input 1: 0 2 4 3 4 0 2 8 Sample Output 1: 0 0 6 8   Sample Input 2: 0 2 4 3 3 0 2 8 Sample Output 2: Invalid Input //PROGRAM #include<stdio.h> int main() { int x1,x2,y1,y2,l1,l2,w1,w2,xmax,xmin,ymax,ymin; scanf("%d %d %d %d",&x1,...

Area Split Pandu, the farmer, has three sons named, Bhima, Arjuna and Nakula. He has also planed for Three field crop rotation and hand over each field to his three sons. His sons are fond of even numbers. So they wanted to split the field only if he is able to split it into 3 even number(wrt area) fields. Pandu was so particular that the difference in area of the fields should be minimum because he equally like his three sons. He would split the field only if it is possible, else he would do the normal farming. Note that it is possible to split only if all three land have positive area. Write a program to help Pandu in spliting the land. Input Format: The first (and the only) input line contains integer that corresponds to the area of the field. Note:  Assume input are positive. Output Format: In the first line of the output, print "Yes", if the field can be divided into three parts as per the requirements of Pandu, else print "No".   If the first line o...

Project predictor In the three-field system the sequence of field use involved an autumn planting of grain (wheat, barley or rye) and a spring planting of peas, beans, oats or barley. The third was left fallow, in order to allow the soil of that field to regain its nutrients The 3 durations(4 months each) are, Duration 1 : 1-4 (all inclusive) Duration 2 : 5-8 (all inclusive) Duration 3 : 9-12 (all inclusive) The 2 crops that were used are,  Crop 1 : Winter Wheat Crop 2 : Beans The initial crops in three fields at month 1are, Field 1 : Winter Wheat Field 2 : Beans Field 3 : Left Fallow Given the month number and field number, write a program to print the crop name. Input Format: The first input is an integer corresponds to month number. The second input is an integer corresponds to field number. Output Format: The output is the string. Sample Input 1: 5 2 Sample Output 1: Winter Wheat   Sample Input 2: 2 3 Sample Output 2: Left Fallow   Sample Input 3: 2 2 Sample Outp...

Plantation A certain crop grown in a sunny and hot climate needs more water per day than the same crop grown in a cloudy and cooler climate. There are, however, apart from sunshine and temperature, other climatic factors which influence the crop water need. These factors are humidity and wind speed. When it is dry, the crop water needs are higher than when it is humid. In windy climates, the crops will use more water than in calm climates. The highest crop water needs are thus found in areas which are hot, dry, windy and sunny. The lowest values are found when it is cool, humid and cloudy with little or no wind. Given 3 crops along with the range of the amount of water required and the temperature range. Crop 1 : Rice – 5 to 10 cm , 20 to 27 degree celcius, all  inclusive. Crop 2 : Wheat – 12 to 15 cm, 21 to 24 degree celcius, all inclusive. Crop 3 : Cotton – 6 to 13 cm, 18 to 30 degree celcius, all inclusive.   Note:  Follow the above crops order. Deter...

Tillage Reduced tillage or conservation tillage is a practice of minimising soil disturbance and allowing crop residue or stubble to remain on the ground instead of being thrown away or incorporated into the soil. 30 % of the residue becomes natural manure. Given the total weight of the residue and the total amount of manure needed for the next crop, Write a C program to determine the amount of manure needed extra. Input Format:  The first line of the input is an integer that corresponds to the total weight of the residue.  The second line of the input is an integer that corresponds to the total amount of manure needed.    Output Format:  An output is a float value that corresponds to the amount of manure needed extra, rounded off to 2 decimal places.  Sample Input: 100 100 Sample Output: 70.00 //C Program #include<stdio.h> int main() { int totweight,totamount; float manure,a; scanf("%d%d",&totweight,...

C Program To Calculate The Revenue The demand for organic food increases every year by 8.9%. Write a program to find the increase in revenue after 3 years. Given the revenue in the first year is ‘x’ crores. Input Format: The first line of the input is an integer that corresponds to the ‘x’ value. Output Format: Output is a float value that corresponds to the revenue after 3 years, rounded off to 2 decimal places. Sample Input: 4 Sample Output: 5.17 //PROGRAM #include<stdio.h> int main() {     int x,i;     float rev;     scanf("%d",&x);     rev=x;     for(i=0;i<3;i++)     {         rev=rev*(1.089);     } printf("%.2f",rev); return 0; }

C Program on Two Field System vs Three Field System Crop rotation is the practice of growing a series of dissimilar or different types of crops in the same area in sequenced seasons. It is done so that the soil of farms is not used for only one set of nutrients. It helps in reducing soil erosion and increases soil fertility and crop yield. In crop rotation technique, there are four strategies. Out of those,           1) Two field system           2) Three field system are popularly followed.        Two Field System: Under a two-field rotation, half the land was planted in a year, while the other half lay fallow. Then, in the next year, the two fields were reversed. Three-field system: Dividing available lands into three parts. One section was planted in the autumn with rye or winter wheat, followed by spring oats or barley; the second section grew cr...
