由 有了这段程序，我可以摆摊为大家算算什么时候出洞钓鱼啦，时间，温度，潮汐，不都是数字嘛！记得把钓点的GPS数字也报上为好。
object BladeCalculation {
def main(args: Array[String]): Unit = {
val target : Int = 1000
val bladeSizes = Array(51,76,102,152,203,254,305,330,381,406,432,457,508,559,635,660,711,762,813,889)
var gap : Int = 1000
var output = ""
for(windowSize <- 1 to 10) {
for(slide <- 0 to bladeSizes.length-windowSize-1) {
val selected = new Array[Int](windowSize)
for (i <- 0 to windowSize - 1) {
selected(i) = bladeSizes(slide + i)
}
println("selected numbers to compare-"+selected.mkString(","))
for (j <- 0 to bladeSizes.length - 1) {
if (!selected.contains(bladeSizes(j))) {
val total = selected.sum + bladeSizes(j)
if (Math.abs(total - target) < gap) {
gap = Math.abs(total - target)
output = selected.mkString(",")+","+bladeSizes(j)
}
}
}
}
}
println("best blade combination choice is ->"+output)
}
}
