获取sheet中存在合并单元格总数,循环绑定值 // 得到一个sheet中有多少个合并单元格 int sheetMergeCount = sheet.NumMergedRegions; ; i < sheetMergeCount; i++) { // 获取合并后的单元格 var range = sheet.GetMergedRegion(i); sheet.IsMergedRegion(range); var cellValue = sheet.GetRow(range.FirstRow).Ge
A permutation \(p\) of size \(n\) is an array such that every integer from \(1\) to \(n\) occurs exactly once in this array. Let's call a permutation an almost identity permutation iff there exist at least \(n - k\) indices \(i (1 ≤ *i* ≤ n)\) such t
