解法一：遍历

没啥好讲的，双重遍历

/**
 * @param {string[]} strs
 * @return {number}
 */
var minDeletionSize = function (strs) {
  let res = 0;
  for (let i = 0; i < strs[0].length; i++) {
    for (let j = 0; j < strs.length - 1; j++) {
      if (strs[j][i] > strs[j + 1][i]) {
        res++;
        break;
      }
    }
  }
  return res;
};
