Finally, ifnis less than0, we calculate the number of digits for the absolute value ofnusingmath.log10(-n)and add2to account for the minus sign, and this is necessary for negative numbers. importmath n=-10ifn>0:digits=int(math.log10(n))+1elifn==0:digits=1elifn<0:digits=int(math...
The first line of the input contains the string received by Kate. The number of digits in this string does not exceed1 000 000. The second line contains the substring ofnwhich Vasya remembers. This string can contain leading zeroes. ...
Input consists of several lines of integer numbers. The first line contains an integer n, which is the number of cases to be tested, followed by n lines, one integer 1 ≤ n ≤ 107 on each line. Output The output contains the number of digits in the factorial of the integers appearing...
