I tried to get the values in a row into an array. For this I used the appscript in googlesheet. After checking the length of this rowtemp array, the answer is 1.
But I want to find the number of children inside. And if the element in "temp" is the same as the one in "rowtemp" then you need to find its column number
I used following code.

    function rangeExa(){
  var ss = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet4");
  var temp = ss.getRange("A11:B22").getValues();
  Logger.log(temp);
  Logger.log(temp.length);
  Logger.log(temp[3][0]);
  var rowTemp = ss.getRange("D25:O25").getValues();
  Logger.log(rowTemp);
  Logger.log(rowTemp.length);
  Logger.log(rowTemp[0][2]);
  Logger.log(rowTemp);
  for(i=0; i<=rowTemp.length; i++){
  if(temp[3][0] == rowTemp[0][i]){
    Logger.log("yessss");
  }return;
  }  
}
