We are given a matrix and the task is to find the greatest difference between the sum of elements in two rows of a matrix. Suppose we have a matrix M[i,j] with i rows and j columns. Let the rows be R0 to Ri-1. The difference will be calculated by subtracting the (sum of elements of Ry) - (sum of elements of Rx), where xMD. If it is so, update MD. Else check is RSum[row]

We are given a positive integer N. The goal is to count the pairs of distinct non-negative positive integers that satisfy the inequality − x*x + y*y < N.We will start from x=0 to x2 lt; N and y=0 to y2 < N . If any x2 + y2 < N, increase count of pairs.Let us understand with examples −Input − n=4Output − distinct pairs= 4Explanation − pairs will be (0, 0), (1, 1), (0, 1), (1, 0). All these satisfy the inequality x2 + y2 < 4Input −n=2Output − distinct pairs= 3Explanation &minus pairs will be (0, 0), (0, ... Read More

The abnormal behavior of C++ programs often leads to program crash. You may have encountered problems like Segmentation fault, Aborted, Floating point exception etc. Following are sample programs that may help you to understand the reasons for a C++ program crash.ExceptionsExceptions in C++ are responses of a program when it encounters an abnormal condition. The program crashes due to such exceptions if they are not handled properly using try-catch blocks. Following program crashes due to divide by zero exception −Example Live Demo#include int main(){    int num1=10;    int num2=0;    int quotient=num1/num2;    printf(" Quotient is: %d", quotient);   ...

Given three inputs first one is “a” which is for the first term of geometric series second is “r” which is the common ratio and “n” which are the number of series whose sum we have to find.Geometric series is a series which have a constant ratio between its successive terms. Using the above stated inputs “a”, “r” and “n” we have to find the geometric series i.e., a, ar, 𝑎𝑟2 , 𝑎𝑟3 , 𝑎𝑟4 , … and their sum, i.e., a + ar + 𝑎𝑟2+ 𝑎𝑟3 + 𝑎𝑟4 +…Inputa = 1 r = 0.5 n = 5Output1.937500Inputa = 2 ...

Given a number n, the task is to print the triangular patterns of alphabets of the length n. First print the n characters then decrement one from the beginning in each line.The triangular pattern of alphabet will be like in the given figure below −Input − n = 5Output Input − n = 3Output Approach used below is as follows to solve the problemTake input n and loop i from 1 to n.For every i iterate j from i to n for every j print a character subtract 1 and add the value of j to ‘A’ .AlgorithmStart In function int pattern( ...

Given a certain cost price(cp) and a selling price(sp) of an unknown product or a service, our task is to find the profit earned or loss suffered using a C program where if the profit is earned should print “Profit” and it’s amount or if the loss is suffered “Loss” and its respective amount or if there is not profit no loss then print “No profit nor Loss”.To find the profit or the loss we generally see whether the selling price(sp) or the price/amount at which a certain thing is sold or the cost price(cp) at which a certain thing ...

Given an integer array arr[] with some elements, the task is to find the product of all the prime number of that numbers.Prime number are those number which are either divided by 1 or the number itself, or a prime number is a number which is not divisible by any other number except 1 and the number itself. Like 1, 2, 3, 5, 7, 11, etc.we have to find the solution for the given array −Input −arr[] = { 11, 20, 31, 4, 5, 6, 70 }Output − 1705Explanation − Prime numbers in array are − 11, 31, 5 their ...

Given the numerator num and denominator den of N fractions, the task is to find the product N fractions and output should be in reduced form.Like in the given figure below we have two fractions ”4/5” and “3/4” we have found the product of those two factions where the numerator of first is multiplied by the numerator of second and the denominator of the first is multiplying the denominator of the second. Now the final result is “12/20” which can be reduced so the output shall be “3/5 ” likewise we have to develop a program to solve the given ... Read More

Given are the two complex numbers in the form of a1+ ib1 and a2 + ib2, the task is to add these two complex numbers.Complex numbers are those numbers which can be expressed in the form of “a+ib” where “a” and “b” are the real numbers and i is the imaginary number which is the solution of the expression 𝑥 2 = −1 as no real number satisfies the equation that’s why it is called as imaginary number.Input a1 = 3, b1 = 8 a2 = 5, b2 = 2Output Complex number 1: 3 + i8 Complex number 2: 5 + i2 ...
