Abundant Number in C ?
An abundant Number (also known as excessive number) is a number in the number theory which itself is smaller than the sum of all its proper divisors. For example, 12 is an abundant Number : divisors 1, 2, 3, 4, 6 , sum =16 >12.The difference between the sum of divisors and the number is called abundance. For above example abundance = 4 => 16 - 12 .To check for abundant number we will find all the factors of the number and add them up. This sum compared with the number show that if the number is abundant or not.PROGRAM ...

An array stores number of same data type. For an array there may arise a situation when you need to store 2-3 values that are same i.e. 3,3,3,3 needs to be stored.For this case, the programing language C has made a simple way to create an array with such repeated value to reduce the workload of the programmer.Syntax[startofRepeatingSeq … EndofRepeatingSeq]number Example : For 3 repeated 5 times ; [0 … 4]3Example#include int main() { int array[10] = {[0 ... 4]3, [6 ... 9]5}; for (int i = 0; i < 10; i++) printf("%d ", array[i]); return 0; }Output3 3 3 3 3 0 5 5 5 5
Read MoreA modified game of Nim in C ?
Modified game of Nim is an optimisation games of arrays. This game predicts the winner based on the starting player and optimal moves.Game Logic − In this game, we are given an array{}, that contains elements. There are generally two players that play the game namly player1 and player2. The aim of both is to make sure that all their numbers are removed from the array. Now, player1 has to remove all the numbers that are divisible by 3 and the player2 has to remove all the numbers that are divisible by 5. The aim is to make sure that ...
Read More0-1 Knapsack Problem in C?
A knapsack is a bag. And the knapsack problem deals with the putting items to the bag based on the value of the items. It aim is to maximise the value inside the bag. In 0-1 Knapsack you can either put the item or discard it, there is no concept of putting some part of item in the knapsack.Sample ProblemValue of items = {20, 25, 40} Weights of items = {25, 20, 30} Capacity of the bag = 50Weight distribution25, 20{1, 2} 20, 30 {2, 3} If we use {1, 3} the weight will be above the max allowed value. ...
Read MoreProgram to build DFA that starts and ends with ‘a’ from the input (a, b)
DFA stands for Deterministic Finite Automata. It is a finite state machine that accepts or a string based on its acceptor.Here, we are going to make a DFA that accepts a string that starts and ends with a. The input is from the set (a, b). Based on this we will design a DFA. Now, Let's discuss some valid and invalid cases that are accepted by a DFA.Strings that are accepted by DFA: ababba, aabba, aa, a.Strings that are not accepted by DFA: ab, b, aabab.ExampleThis program check for a string that starts and ends with a. This DFA will ...
