    Hi, Can someone tell what is the issue with this code.I get RunTimeError for 7th test case . Its not TLE Error

    def getexpression(arr,operators,curInd,curresult,expr):

    if curInd == len(arr):
         if curresult%101 ==0:
             return([True,expr])
         else:
             return([False,""])

    resultTillnow=curresult

    expTillnow=expr

  for op in operators:
    val2=arr[curInd]
    if op=="ADD":
        result=resultTillnow+val2
        oper="+"
    elif op=="MUL":
        result=resultTillnow*val2
        oper="*"
    else:
        result=resultTillnow-val2
        oper="-"
    nexpr=expTillnow+oper+str(val2)    
    stat,e=getexpression(arr,operators,curInd+1,result,nexpr)
    if stat:
        return([stat,e])
return([False,""])

    def arithmeticExpressions(arr):

    operators=['ADD','MUL','SUB']

stat,expr = getexpression(arr,operators,1,arr[0],str(arr[0]))  

    if stat:

    return expr
    tat:
    return(expr)
   return exprelse:
    return("")
