Test caes 3 and 4 are shown as being failed.
please help me with the errors in the code
hi @karanaggarwal708_71435e604edb5689,
code is absolutely correct just dont use power function
here’s the updated one https://ide.codingblocks.com/s/658505
reason :
The problem is that double (and floating-point numbers in general) aren’t exact and the math functions in the standard library also use approximate formulae to do the calculations. If you call pow(2, 10) , you may get 1023.999375 , for example (which is then, depending on the context, may be truncated down to 1023 ).
hope this solves the issue
