Applying a function each respective 2 elements of an array
I have an array like(In my real problem my data structs is more complex ) : auto a = [2,3,4,5,6,7]; I want to apply a operation in a fashion like : [ 2 , 3 ] --> apply foo and get return result -1 [ 3 , 4 ] ---> -1 [ 4 , 5 ] ---> -1 and so on... operation might be : int foo ( int a, int b) { return a - b; } So my expected result is [-1,-1,-1,-1,-1] I tried fold but fold add up the result of the last operation. Range utilities like "chunks" does not help because "chunks" transforms the array into a range like [2,3],[4,5],[6,7]. Can I avoid for loops and solve my problem with std algorithms or ranges ?
