Again part of "coding" test for non-programmers

What number is non-standard if standard means all integers.

Answers included 99, -0. 11.2, and -16. Unsure if -0 is an integer. No answer was an option as well.

Edit: that non-standard was not in the original question. I do not recall the question exactly, but it revolved around whether -0 is an integer.

A program removes all non-numeric characters until it reaches a second non-numeric and then stops. "+3.4"=3

What would result when "1.2" was entered?

1 was not an option. 1.2 was not.

No answer was an option. Chose no answer.

I did pass the test with many "no answers".

Which is a true statement?

if both true, A&B=True

A&B=False if only one false

A^B=True if only one True

Which of these 5 is not true? The all seemed fairly obvious except

1) A&B^C

2) 8&0+0=0

3 others I forgot

One was a math problem without an =

the challenge was not the logic but whether

one can classify an equation with 0=0 or answer 8 as

true or false.

No answer was available.

What is the remainder of normal fraction?

# = Modulo

Several problems used the # symbol defined as

the remainder 4 / 3 =1

One question asked 3 /4 another 1/2

another had 0/0

You had to know not only modulo but whether it

is usable for a normal fraction.

Please update if you take the test

update

Part of coding test for non-programmers.

‘ means not. It converts a character to null in a string but converts the character to 0 in an operation

1=John 2= Jane 3= Does

“’123” = ?

Jane3Does was the closest answer. It seemed wrong because of the 3 in there.

I'm sorry i forgot the other answers, but they were

equally illogical.

‘ means not. It converts a character to null in a string but converts the character to 0 in an operation

‘5 means null whereas ‘5+1=1

Which one of these is true?

Cannot recall the options; they all appeared false.

I put the last option, but couldn’t figure it out.

‘(‘5)=0?

Part of coding test for non-programmers.

Holy Water is concatenated by “Holy “.”Water” or “Holy”.” Water” Watch the space.

How would you spell "Holy water" given “Holy”=God and HOH=”Water”.

1) God.HOH

2) God.” “.HOH

3) God”.” HOH

4) Forgot others

User inputs a series of numbers and terminates the series by a zero. Your program should find the first three maximum values in the series and exclude them from the series and compute the average of the remaining numbers. (excluding zero as well)

Ex - 3, 7, 12, 2, 25, 8, 9, 13, 10, 0

First three maximum numbers = 25, 13, 12

Average of the rest = (3 + 7 + 2 + 8 + 9 + 10) / 6 = 6.5

User inputs a sequence of digits. Every digit is a keystroke, that is equivalent to some character out of a sequence of characters. Digit zero and five mean NULL. The table is given below

0 - NULL

1 - v, t, f, r, q

2 - f, t, k

3 - w, z, b, g

4 - r, s

5 - NULL

6 - f, i, r

7 - p

8 - l, o

9 - p

Generate all possible character sequence for a given sequence of digits.

Ex - If the user input 9801, your program should generate

{plv, plt, plf, plr, plq, pov, pot, pof, por, poq} (not necessarily in this order).

This problem is somewhat similar to the SMS problem. It basically boils down to generating a cartesian product of the character sets corresponding to keys.

Find the seed of a number.

Eg : 1716 = 143*1*4*3 =1716 so 143 is the seed of 1716. find all possible seed for a given number.

Given the start and an ending integer as user input, generate all integers with the following property.

Example : 123 , 1+2 = 3 , valid number

121224 12+12 = 24 , valid number

1235 1+2 = 3 , 2+3 = 5 , valid number

125 1+2 <5 , invalid number

You are a hacker and need to find possible passwords given the length of the password and that it is a well-ordered number (eg., 123 is well-ordered as 1<2<3 and 213 is not well-ordered as 2<1<3 is NOT true)

write a program in c# or java or c that prints saddle points in a N by N Matrix.

saddle point is nothing but a cell values which has greater value among all the cell values in that row as well as it should be the smallest value among the column in which it is found......???

Print continuous alphabets from a sequence of arbitrary alphabets

For example:

Input: abcdefljdflsjflmnopflsjflasjftuvwxyz

Output: abcdef; mnop; tuvwxyz

Input: AbcDefljdflsjflmnopflsjflasjftuvWxYz

Output: abcdef; mnop; tuvwxyz

Determine whether a number is colorful or not. 263 is a colorful number because (2,6,3,2x6,6x3,2x3x6) are all different whereas 236 is not because (2,3,6,2x3,3x6,2x3x6) have 6 twice. So take all consecutive subsets of digits, take their product and ensure all the products are different

There is a game they termed as Mingo. A random generator (like a speaker standing in a group housie game calls out a number) generates out any number from 1 to 1000.

There is a 10X10 matrix. A random generator assigns values to each block of this matrix(within 1 to 1000 obviously).

Whenever, a row or a column or a diagonal is fully filled in this 10x10 from the numbers called out by the speaker, its called a 'Mingo'.

Write a program that will find first Mingo, then second Mingo, then thirds Mingo...and so forth.
