We know that the excel column numbers are alphabetic. It starts from A, and after Z, it will AA, AB, to ZZ, then again AAA, AAB, to ZZZ and so on. So column 1 is A, column 27 is Z. Here we will see how to get the column letter if a number of columns is given. So if the column number is 80, then it will be CB.Suppose we have a number n, and its value is 28, then we need to take a reminder with 26. If the remainder is 0, then the number is 26, 52 and ...

Suppose we have an array; we have to check whether given number x is the majority element of that array or not. The array is sorted. One element is said to be the majority element when it appears n/2 times in the array. Suppose an array is like {1, 2, 3, 3, 3, 3, 6}, x = 3, here the answer is true as 3 is the majority element of the array. There are four 3s. The size of the array is 7, so we can see 4 > 7/2.We can count the occurrences of x in the array, and ... Read More

Program DescriptionFloyd's triangle is a right-angled triangular array of natural numbers, used in computer science education. It is named after Robert Floyd. It is defined by filling the rows of the triangle with consecutive numbers, starting with a 1 in the top left corner1                               15 14 13 12 11 2 3                             10 9 8 7 4 5 6                         6 ...

Program DescriptionA pyramid is a polyhedron formed by connecting a polygonal base and a point, called the apex. Each base edge and apex form a triangle, called a lateral face. It is a conic solid with polygonal base. A pyramid with an n-sided base has n + 1 vertices, n + 1 faces, and 2n edges. All pyramids are self-dual.AlgorithmAccept the number of rows from the user to form pyramid shape Iterate the loop till the number of rows specified by the user: Display 1 star in the first row Increase the number of stars based on the number of ...

Program DescriptionA pentatope number is a number in the fifth cell of any row of Pascal's triangle starting with the 5-term row 1 4 6 4 1 either from left to right or from right to left.The first few numbers of this kind are1, 5, 15, 35, 70, 126, 210, 330, 495, 715, 1001, 1365Pentatope numbers belong in the class of figurate numbers, which can be represented as regular, discrete geometric patterns. The formula for the nth pentatopic number is$$\left(\begin{array}{c}n+3\ 4\end{array}\right)=\left(\frac{n(n+1)+(n+2)+(n+3)}{24}\right)=\left(\frac{n^2}{4!}\right)$$AlgorithmAccept the Nth Term from the User to find the Pentotope Numbers.Use the formula$$\left(\begin{array}{c}n+3\ 4\end{array}\right)=\left(\frac{n(n+1)+(n+2)+(n+3)}{24}\right)=\left(\frac{n^2}{4!}\right)$$Example/* Program to print pentatope numbers ...

Suppose we have an array A, here A[i] is indicating the price of a given stock on day i. We have to find the maximum profit. We can complete as many transactions as we like. (Transaction means to buy and sell stocks). But we have to keep in mind that we may not engage in multiple transactions at the same time. So we have to sell the stock before buying the new one.Suppose the array is like A = [7, 1, 5, 3, 6, 4], then the result will be 7. As we can see, if we buy on day ... Read More

Suppose we have an array A, here A[i] is indicating the price of a given stock on day i. We have to find the maximum profit. We can complete at most one transaction. (Transaction means to buy and sell stocks). But we have to keep in mind that we may not engage in multiple transactions at the same time.
