I have thousands of matching pairs of data under Col A and Col B. I am trying achieve the following: for every pair of data, there will be an “exact opposite pair” somewhere below.
\nSee example below:<\/p>\n
A B
\n100 162*
\n300 159
\n268 465
\n162 100*<\/p>\n
Note: In this case, the AB pair, marked with an asterisk (*), has an “exact opposite pair” below, also marked with an asterisk (*).<\/p>\n
How can I search the entire list and ensure that for every AB pair, there is an “exact opposite pair” within the list? And if there isn’t, how can I add the “exact opposite pair” to the list in a quick and efficient way?<\/p>\n
Much needed help.
\nThank you.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"inline_featured_image":false,"iawp_total_views":12},"question-category":[53],"question_tags":[],"class_list":["post-8385","question","type-question","status-publish","hentry","question-category-office"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/question\/8385","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/question"}],"about":[{"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/types\/question"}],"author":[{"embeddable":true,"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/comments?post=8385"}],"wp:attachment":[{"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/media?parent=8385"}],"wp:term":[{"taxonomy":"question-category","embeddable":true,"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/question-category?post=8385"},{"taxonomy":"question_tags","embeddable":true,"href":"https:\/\/computing.net\/answers\/wp-json\/wp\/v2\/question_tags?post=8385"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
