in the good function bool good(double x){ double temp=( x*x + sqrt(x) ); if(temp-c>0) return 0; else if(temp-c<=0) return 1; }
why are we doing,
if(temp-c>0) return 0; else if(temp-c<=0) return 1;
instead of return temp-c== 0;

Because binary search is monotonic.
can u please elaborate a little more, I am having a hard time understanding why <= 0
If you want to check for every possible value of x then you can write return temp-c==0 in good funtion. but that method gives you tle.so for reducing time limit you need to apply here binary search and making good funtion according to bs.
