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; ...

In this problem, we are given an integer N. The task is to find n-th term in series 9, 33, 73, 129....Let’s take an example to understand the problem, InputN = 4Output129ExplanationThe series upto nth term is 9, 33, 73, 129...Solution ApproachThe solution to the problem lies in finding the nth term of the series. We will find it mathematically and then apply the general term formula to our program.First let’s subtract the series by shifting it by one.Sum = 9 + 33 + 73 + … + t(n-1) + t(n) - Sum = 9 + 33 + 73 + ...

In this problem, we are given an integer N. The task is to find n-th term in series 7, 15, 32....Let’s take an example to understand the problem, InputN = 6Output281ExplanationThe series upto nth term is 7, 15, 32, 67, 138, 281Solution ApproachThe solution to the problem lies in decoding the series. You can see the series is a mix of series.The subtracting the values, T(2) - T(1) = 15 - 7 = 8 T(3) - T(2) = 32 - 15 = 17 So, T(2) = 2*T(1) + 1 T(3) = 2*T(2) + 2 T(n) = 2*T(n-1) + ... Read More
In this problem, we are given an integer N. The task is to find n-th term in series 1 2 2 3 3 3 4….Let’s take an example to understand the problem, InputN = 6Output3ExplanationThe series upto nth term is 1, 2, 2, 3, 3, 3, ...Solution ApproachA simple approach to solve the problem is by using a nested loop. The outer for loop is from 1 to n. And the inner loop is from 1 to i (iterator of outer loop). For each iteration in the inner loop, count the number of elements of the series and return the ...

In this problem, we are given a binary tree and an integer N. The task is to find the n-th node in inorder traversal of a Binary Tree.A binary tree has a special condition that each node can have a maximum of two children.Traversal is a process to visit all the nodes of a tree and may print their values too.Let’s take an example to understand the problem, InputN = 6Output3Explanationinorder traversal of tree : 4, 2, 5, 1, 6, 3, 7Solution ApproachThe idea is to use the in-order traversal of the binary tree which is done by using recursive ...

CSS object-fit and object-position property helps us crop images and specify how it is displayed in an element.The syntax of CSS object-fit property is as follows −Selector { object-fit: /*value*/ object-position:/*value*/ }ExampleThe following examples illustrate CSS object-fit property. Live Demo img { object-fit: cover; } img:last-of-type { object-fit: contain; } cover contain OutputThis will produce the following result −Example Live Demo div { border: 1px solid blue; width:100%; height:300px; } img { float:left; width:50%; height:100%; object-fit:cover; object-position: 20px -10px; } OutputThis will produce the following result −Effect of resizing
