The IntlChar isgraph()function checks that the entered value is a graphic character or not.Syntaxbool IntlChar::isgraph (val)Parametersval − An integer or character encoded as a UTF-8 string.ReturnThe IntlChar isgraph() function returns TRUE of val is a graphic character.ExampleThe following is an example −OutputThe following is the output −bool(true) bool(false) bool(false) bool(true)
The IntlChar isMirrored()function is used to check whether the entered value contains Bidi_Mirrored property or not.Syntaxbool IntlChar::isMirrored (val)Parametersval − An integer or character encoded as a UTF-8 string.ReturnThe IntlChar isMirrored()function returns TRUE if the entered value has the Bidi_Mirrored propertyExampleThe following is an example −OutputThe following is the output −bool(true) bool(true) bool(false) bool(false)
Suppose we have an array A[] with n positive elements. We have to create another array B, such that B[i] is XOR of all elements of A[] except A[i]. So if the A = [2, 1, 5, 9], then B = [13, 14, 10, 6]To solve this, at first we have to find the XOR of all elements of A, and store it into variable x, then for each element of A[i], find B[i] = x XOR A[i]Example Live Demo#include using namespace std; void findXOR(int A[], int n) { int x = 0; for (int i = 0; ...

TheIntlChar::isblank() function checks whether the entered value isblank or horizontal space character.SyntaxIntlChar::isblank (val)Parametersval − An integer or character encoded as a UTF-8 string.ReturnThe IntlChar::isblank() function returns TRUE if the entered value isblank or horizontal space character.ExampleThe following is an example −OutputThe following is the output −bool(true) NULL bool(false) bool(false)
The IntlChar::islower() function check whether the given input character is a lowercase character or not.Syntaxbool IntlChar::islower(val)Parametersval − A character encoded as a UTF-8 string.ReturnThe IntlChar::islower() function returns TRUE if the entered value is a lowercase character.ExampleThe following is an example −OutputThe following is the output −bool(true) bool(false)
Suppose we have an array A[], with n elements. We have to find another array B[], whose size is n+1, such that GCD of B[i] and B[i + 1] is A[i]. If there are multiple solutions, then print one of them whose array sum is minimum. So if A = [1, 2, 3], then output will be [1, 2, 6, 3]When A has only one element say K, then B = [K, K]. So the B[0] will be A[0]. Now consider we are done up to index i, so we have already processed index i, and calculated B[i + 1]. ... Read More
Suppose we have an array A[], with n elements. We have to construct the binary tree from the array in level order traversal. So the elements from the left in the array will be filled in the tree level-wise starting from level 0. So if the array is like A = [1, 2, 3, 4, 5, 6], then the tree will be like below:If we see closer, we can find that when the parent is present at index i, then its two children will be at index (2i + 1), and (2i + 2). Thus we can insert left and ... Read More
The slideToggle() method in jQuery is used to toggle between the slideUp() and slideDown() methods.SyntaxThe syntax is as follows −$(selector).slideToggle(speed, easing, callback)Above, the parameter speed is the speed of the slide effect. Here, easing is the speed of the element in different points of the animation, whereas callback is a function to be executed after slideToggle() completes.Let us now see an example to implement the jQuery slideToggle() method −Example Live Demo $(document).ready(function(){ $("button").click(function(){ $("p").slideToggle(); }); }); Exam Info Examination begins on 24th December. ...

Here we will see that is the upper_bound() function in C++ STL. This function returns an iterator that points to the first element in the container, which is considered to go after val. The syntax is like:iterator upper_bound (const value_type& val); const_iterator upper_bound (const value_type& val) const;The return value is an iterator, pointing to the first element in the container which is considered to go after val.Example Live Demo#include #include using namespace std; int main () { set myset; set::iterator itlow, itup; for (int i = 1; i < 10; i++) myset.insert(i*10); itup = myset.upper_bound ...

To convert an image to Grayscale in CSS3, use the grayscale value for filter property.ExampleLet us see an example − Live Demo img.demo { filter: brightness(120%); filter: contrast(120%); filter: grayscale(130%); } Spring Framework Learn MySQL Below image is brighter and has more contrast than the original image above. With that the image is in grayscale: Output
