Maximum number of 2×2 squares that can be fit inside a right isosceles triangle in C
We are given a right isosceles triangle where we need to find the maximum number of 2×2 squares that can fit inside it. An isosceles triangle has two sides of equal length, and in a right isosceles triangle, the base and height are perpendicular and equal to each other. Base Height The key insight is that from the corner triangular areas, we need to subtract ...
Read MoreCreate a disabled look of a button with CSS
To create a disabled button look in CSS, you can use the opacity property to make the button appear faded and less interactive. This visual effect helps users understand that the button is not functional. Syntax selector { opacity: value; } Example: Basic Disabled Button Look You can try to run the following code to create a disabled look of a button − .btn1 { background-color: #4CAF50; ...
Read MoreCount number of 1s in the array after N moves in C
We are given an array of size N. The array has all 0's initially. The task is to count the number of 1's in the array after N moves. Each Nth move has a rule associated with it − 1st Move − Change element at positions 1, 2, 3, 4... 2nd Move − Change element at positions 2, 4, 6, 8... 3rd Move − Change element at positions 3, 6, 9, 12... In each move, we flip the elements (0 becomes 1, 1 becomes 0) at the specified positions. Let's understand with examples. Syntax ...
Read MoreCreate a Vertical Button Group with CSS
The vertical button group in CSS allows you to stack buttons one below the other, creating a clean and organized navigation or action menu. This layout is useful for sidebars, navigation panels, or any interface where you need buttons arranged vertically. Syntax .button-group .button { display: block; width: 100%; } Example The following example creates a vertical button group with styled buttons ? .mybtn .button { background-color: orange; ...
Read MoreMaximum binomial coefficient term value in C
In C, finding the maximum binomial coefficient term for a given positive integer 'N' involves calculating all binomial coefficients nCr and determining the largest value among them. The binomial coefficient series is nC0, nC1, nC2, ..., nCr, ..., nCn-2, nCn-1, nCn. Syntax nCr = n! / (r! * (n - r)!) For N=4: 4C0=1, 4C1=4, 4C2=6, 4C3=4, 4C4=1. Maximum coefficient is 6. For N=5: 5C0=1, 5C1=5, 5C2=10, 5C3=10, 5C4=5, 5C5=1. Maximum coefficient is 10. Method 1: Using Pascal's Triangle Approach This method builds Pascal's triangle using dynamic programming to calculate binomial ...
Read MoreSet the color of the rule between columns with CSS
The CSS column-rule-color property sets the color of the rule (line) that appears between columns in a multi-column layout. This property is used in conjunction with column-rule-style to create visible separators between columns. Syntax selector { column-rule-color: color; } Possible Values ValueDescription colorAny valid CSS color value (hex, rgb, rgba, named colors, etc.) initialSets the property to its default value inheritInherits the color from the parent element Example: Orange Dashed Column Rule The following example creates a 4-column layout with orange dashed rules between columns − ...
Read MoreShorthand property for setting all the column-rule-* properties
The CSS column-rule property is a shorthand property for setting all the column rule properties in one declaration. It allows you to define the width, style, and color of the line that appears between columns in a multi-column layout. Syntax selector { column-rule: width style color; } Possible Values PropertyValuesDescription column-rule-widththin, medium, thick, lengthSets the width of the column rule column-rule-stylenone, solid, dashed, dotted, double, etc.Sets the style of the column rule column-rule-colorcolor name, hex, rgb, rgbaSets the color of the column rule Example The following ...
Read MoreMaximize the difference between two subsets of a set with negatives in C
We are given an array of positive and negative integers. The task is to find the maximum difference between two subsets where one contains positive numbers and the other contains negative numbers. The maximum difference is achieved by taking all positive numbers in one subset and all negative numbers in the other subset, then calculating (sum of positives) − (sum of negatives). Since subtracting negatives effectively adds them, we can convert all negatives to positives and sum all elements. Syntax int maximizeSubsetDifference(int arr[], int n); Example Input and Output Input − Arr[] = { ...
Read MoreHow to fill columns with CSS
The CSS column-fill property controls how content is distributed across multiple columns when using CSS multi-column layout. This property determines whether columns should be balanced in height or filled sequentially. Syntax selector { column-fill: value; } Possible Values ValueDescription balanceContent is distributed evenly across all columns (default) autoColumns are filled sequentially, one after another balance-allBalance content across all columns including the last fragment Example: Balanced Column Fill The following example demonstrates the balance value, which distributes content evenly across columns − ...
Read MoreMaximum and minimum of an array using minimum number of comparisons in C
We are given an array of integers. The task is to find the minimum and maximum elements of the array using the minimum number of comparisons possible. Syntax void findMinMax(int arr[], int n, int *min, int *max); Algorithm To minimize comparisons, we use an optimized approach − If array has only one element, both min and max are that element For arrays with multiple elements, compare first two elements to initialize min and max Then traverse remaining elements, comparing each with current min and max This approach requires approximately 1.5n comparisons instead ...
