clearing the array , which would have some values in it, would solve this, and this is because when you print it, and there are some other values in it, you get them printed too for( int i = 0; i < maxL; ++i ) newdata[i] = (char)0; solve it completely . EDIT: And to … Read more

The average case complexity for both cases is O(n). if k is the number of times the first if fails, then the number of comparisons is 2*n – 2 – k. maxmin(a,n,max,min){ max=min=a[1]; for i=2 to n do{ // goes through the loop n-1 times if a[i]>max then max:=a[i]; // out of n-1 times succeeds … Read more

Try this, basically you can concatenate the three strings as a single string and use the combined string as the input for the md5 function >>> import hashlib >>> value1 = “value1” >>> value2 = “value2” >>> value3 = “value3” >>> hashlib.md5(value1 + value2 + value3).hexdigest() ‘ceba206ca4802a60ca07a411905111b8’ solved MD5 with more than one parameter [closed]
The Law of Excluded Middle is incredibly useful for formal reasoning about if statements. The two choices that you have in your code are as follows: n is equal to 1, and n is not equal to 1. There is no third “middle” state in this logic. Now let’s go back to your code, and … Read more
