Number of CyclesDescriptionwe know that in programming, we often need to take into account the complexity of time, especially for the loop part. For example, if a for (i=1;iInputThere are T group case,t Outputfor each case, output a value that represents the total amount of computation, perhaps the number is large, then you only need to output the remainder of the 1007 left.
