# # Your prevIoUs Plain Text content is preserved below:# # # Boolean search is powerful in sourcing and recruiting.# We will use machine learning prediction to provIDe relations among skills. Now we need a function to transfer those relations to a string with correct boolean format.# # Example1:# input: [["java", "python"], ["machine learning", "deep learning"]]# output: ("java" OR "python") AND ("machine learning" OR "deep learning")# # Example2:# input: [[["java", "maven", "spring"], "python"], ["machine learning", "deep learning"]]# output: (("java" OR "maven" OR "spring") AND "python") AND ("machine learning" OR "deep learning")

// let a = [[["java", "maven", "spring"], "python"], ["machine learning", "deep learning"]]let a = [["java", "python"], ["machine learning", "deep learning"]];// [["java", "maven", "spring"], "python"]function subString(arr, dep=0){  if(arr.every((x)=>typeof x === 'string')){    return `(${arr.map(x=>`"${x}"`).join(' OR ')})`;  }    let s = arr.map(a => {    if(Array.isArray(a)){      return subString(a, 1);    }    return `"${a}"`;  }).join(' AND ');  return dep ? `(${s})` : s;}console.log(subString(a))
