Hi Experts, Given an unsorted array and a number n, find if there exists a pair of elements in the array whose difference is n. Return count of such pairs. Example k=4 and a[]={7,623,19,10,11,9,3,...

aCount up the dots. The only important feature is whether the number is odd or even. The traditional method is to connect pairs with a line, working from right to left. That makes it simple to tell if the number is even or odd. Geomancy is of Islamic origin, so all steps are worked...
Javascript Program to Count pairs with given sum - Given an array of n integers and a given sum S, write a JavaScript program to find the total number of pairs of elements in the given array with a sum equal to S. Counting pairs with a given sum is a com

Use theSUBTOTALfunction to count the number of values in an Excel table or range of cells. If the table or range contains hidden cells, you can use SUBTOTAL to include or exclude those hidden cells, and this is the biggest difference between SUM and SUBTOTAL functions. ...

At this point, let's do some more works first. Before finding how many pairs E has, insert all elements in left of it in a trie, so you have inserted A B C D at this point. Now, we wanted to find a number among these whose leftmost bit is 0, so that when xor'ed with E,...
