In this problem, we are given an element N. We need to find the next greater number with the same set of digits. We need to find the smallest number with the same digit which is greater than N.Let’s take an example to understand the problem, InputN = "92534"Output92543Solution ApproachA simple solution to the problem to find the next greater element is by the following approach −Traverse the number from least significant bit to most significant bit. And stop when the current element is smaller than the last element.After this search for the smallest element in the remaining array. And ... Read More
In this problem, we are given an element N. we need to find the N’th number in a number system with only 3 and 4.The number system consists of elements 3, 4, 33, 34, 43, 44, 333, 334, 343, 344, …Let’s take an example to understand the problem, InputN = 6Output44ExplanationThe numbers of the number system are − 3, 4, 33, 34, 43, 44...Solution ApproachThe number system is similar to the binary number system but the number 0 is replaced by 3 and number 1 is replaced by 4.Let’s say this as sBinary.So, number Nth number is (n-1)’s Sbinary conversion.With ...

In this problem, we are given two sorted arrays arr1[] and arr2[] of size m and an element N. Our task is to Find Nth item in a set formed by the sum of two arrays.Code description − Here, we will create a set that consists of the sum of element one of arr1 and one of arr2 i.e. sum = arr1[i] + arr2[j], where are i , j < m. For N, we need to find the value of the Nth element of the set.Let’s take an example to understand the problem, Inputarr1[] = {3, 1, 5} , arr2[] = ... Read More
In this problem, we are given an array sum[] consisting of a sum of (n-1) variables given as, Sum[1] = x2 + x3 + x4 + … xn Sum[2] = x1 + x3 + x4 + … xn . . Sum[i] = x2 + x3 + x4 + … x(i-1) + x(i+1) + … + xn . . Sum[n] = x1 + x2 + x3 + … x(n-1) Our task is to find the value of x1, x2, ... xn.Let’s take an example to understand the problem, Inputsum[] = {6, 6, 6, 6, 6, 6, 6}Outputx1 = 1, x2 = ... Read More
In this problem, we are given an integer N. The task is to find the n-th term in series 3, 9, 21, 41, 71...Let’s take an example to understand the problem, InputN = 7Output169ExplanationThe series is 3, 9, 21, 41, 71, 169...Solution ApproachA simple solution to the problem is by finding the general term of the series. The general term can be found by observing the series a bit. It is, $$T(N) = \sum n^{2} + \sum n + 1$$We can directly use the formula for the sum of square of first n natural numbers, first n natural number and ... Read More
In this problem, we are given an integer N. The task is to find the n-th term in series 2, 10, 30, 68, 130...Let’s take an example to understand the problem, InputN = 7Output350ExplanationThe series is 2, 10, 30, 68, 130, 222, 350...Solution ApproachA simple solution to the problem is by finding the general term of the series. Here, the Nth term of the series is N^3 + N. This is found by subtracting the current element with the current index.For i, i = 1, T(1) = 2 = 1 + 1 = 1^3 + 1 i = 2, T(1) ... Read More
In this problem, we are given an integer N. The task is to find the n-th term in series 1, 3, 6, 10, 15, 21, 28....Let’s take an example to understand the problem, InputN = 7Output28ExplanationThe series is 1, 3, 6, 10, 15, 21, 28...Solution ApproachA simple solution to the problem is by finding the general term of the series. On observing the series we can see that the ith number of the series is the sum of (i-1)th term and i.This type of number is called triangular number.To solve the problem, we will loop till n, and for each ...

In this problem, we are given an integer N. The task is to find the n-th term in series 1, 4, 27, 16, 125, 36, 343....Let’s take an example to understand the problem, InputN = 7Output343ExplanationThe series is 1, 4, 27, 16, 125, 36, 343…Solution ApproachA simple solution to the problem is by finding the general term of the series. This series comprises two different series one at odd terms and one at even terms. If the current element index is even, the element is square of its index. And if the current element index is odd, the element is ... Read More
A webpage with fluid sidebar and main content area is created by setting the size of html and body to 100%.The following example illustrates this.Example Live Demo html,body { height: 100%; color: white; font-size: 2em; line-height: 200px; } #parent { display: table; width: 100%; height: 100%; } #side { display: table-cell; background-color: turquoise; width: 20%; vertical-align: top; box-shadow: inset 0 0 10px black; } #main { display: table-cell; width: 80%; background: url("https://images.unsplash.com/photo-1611944444060- b50a1d80cfe6?crop=entropy&cs=tinysrgb&fit=crop&fm=jpg&h=800&ixlib=rb1.2.1&q=80&w=600"); } Side Main OutputThis will produce the following result −
A full-height page with a fixed sidebar and scrollable content area can be created by setting the height to 100% and applying proper positioning of elements.The following example illustrates the above.Example Live Demo .main { margin-left: 140px; font-size: 200%; padding: 0 3%; } section { height: 400px; background-color: tomato; } .sidebar { height: 100%; width: 140px; top: 0; left: 0; position: fixed; background-color: darkslategrey; padding-top: 20px; } .sidebar a { display: block; padding: 2% 4%; text-decoration: none; color: lightblue; font-size: 1.4em; ...
