对于groovy,我想在列表列表(不同大小)上进行转置。
def mtrx = [
[1,2,3],
[4,5,6,7]
]
预期结果:
[[1,4],[2,5],[3,6],[null,7]]
或
[[1,4],[2,5],[3,6],[7]]
方法.transpose()工作正常,工作正常,但不相等 - 某些元素被截断。
我的代码是:
def max = 0
def map = [:]
def mapFinal = [:]
def row = 0
def mtrx = [
[1,2,3],
[4,5,6,7]
]
mtrx.each{it->
println it.size()
if(max < it.size()){
max = it.size()
}
}
def transposed = mtrx.each{it->
println it
it.eachWithIndex{it1, index->
println it1 + ' row ' + row + ' column ' +index
mapFinal[row+''+index] = it1
map[index+''+row] = it1
}
row++
}
println map
println mapFinal
答案 0 :(得分:4)
尝试
(0..<(mtrx*.size().max())).collect {
mtrx*.getAt(it)
}
