[jira] [Updated] (ARROW-11368) [C++][Compute] Return scalar if only one mode or quantile is required

     [ https://issues.apache.org/jira/browse/ARROW-11368?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Yibo Cai updated ARROW-11368:
-----------------------------
    Description: Mode and quantile kernels support returning multiple values and always return array to hold multiple values. If only one value is required, an array of size 1 is returned. It's better to return a scalar instead in this case.  (was: Mode and quantile kernels support returning multiple values and always return vector to hold multiple values. If only one value is required, a vector of size 1 is returned. It's better to return a scalar instead in this case.)
