C++Sequence algorithms

Calculate changes between successive readings ↗

C++: adjacent_difference keeps the first value and then writes each difference from its predecessor.

C++✓ Tested

C++Sequence algorithms

Calculate cumulative totals ↗

C++: partial_sum writes the sum of each input prefix to the output sequence.

C++✓ Tested

C++Sequence algorithms

Calculate the dot product of two vectors ↗

C++: inner_product multiplies corresponding elements and accumulates them from a chosen seed.

C++✓ Tested

C++Sequence algorithms

Count elements satisfying a predicate ↗

C++: count_if counts matches without constructing a filtered collection.

C++✓ Tested

C++Sequence algorithms

Find both extremes in one algorithm call ↗

C++: Check for a nonempty input before dereferencing the returned iterators.

C++✓ Tested

C++Sequence algorithms

Find the first value satisfying a condition ↗

C++: Compare the returned iterator with end before dereferencing it.

C++✓ Tested

C++Sequence algorithms

Merge two sorted sequences ↗

C++: Both inputs must use the same ordering before merge is called.

C++✓ Tested

C++Sequence algorithms

Rotate a sequence around a selected position ↗

C++: rotate places the element at the middle iterator first while preserving the two segment orders.

C++✓ Tested

C++Sequence algorithms

Test any and all elements with predicates ↗

C++: These algorithms stop as soon as their result is known.

C++✓ Tested

C++Sequence algorithms

Transform a vector into a separate result ↗

C++: Pre-size the output before writing through its iterator.
