Convert a list of maps to one map in Groovy

Question

I have a list of cards as shown below:

List mapOne = [[hi:1], [hello:2],[xyx:4]]

This card needs to be converted to one card as shown below

Map resultMap=[hi:1, hello:2,xyx:4]

Are there any built-in functionality in Groovy?

Another option sum

:

groovy:000> [[hi:1], [hello:2], [xyx:4]].sum()
===> [hi:1, hello:2, xyx:4]

Just do:

Map resultMap = mapOne.collectEntries()
