Greedy works fine all test pass. Except the values having one value after decimal like 0.1, 4.5. Because in round function I'm using 100 as multiplier, the values become 10, 450 instead of 1 and 45. 

bal = roundf(balu * 100);

Any clue how can I use it for both the inputs, for 0.54 as well as 0.3.

  • Try simply taking input and storing in a float and then multiply by 100, check if it works.

Are you making an arithmetic error? You state, "in round function I'm using 100 as multiplier, the values become 10, 450 instead of 1 and 45." However, that's exactly what 0.1 and 4.5 should become: 10 and 450, not 1 and 45.

In other words, $0.1 is 10 cents, and $4.5 is 450 cents.

Use round function, not roundf

  • You must use round function and bal should be an integer...
