> Operator Strength Reduction is an optimization that reformulates costly operations in terms of less expensive ones.
> The simplest possible example is the following:
> before:
> int sum = 0;
> for(int i=0; i<10;i++){
> int temp = i * 10;
> sum+=temp
> }
> after:
> int sum = 0;
> for(int j=0; j<100; j+=10){
> sum+=j
> }
