A famous software company held a job fair today. It is interesting to have such a question. The recruitment questions are as follows:
Donald + Gerald ---------- Robert has a total of 10 letters. Each letter represents one of the 0-9 Arabic numerals. If R = 7 is known, calculate the numbers represented by the other 9 letters. The answer is as follows: (1) 2D = T, meaning T is an even number. (2) 2L = r, think R = 7, and 2L is an even number, which indicates that 2D must have an inner,
So D> = 5, Which means 2L + 1 = r and r = 7. Therefore, l has two possibilities.
1. L = 3. 2.l= 8
When l = 3 is set:
(3)2a = e indicates that E is an even number. (4) N + R = B (5) 0 + E = 0 indicates that E has two possibilities:
1. E = 0. 2.e= 9. If Step 3 shows that E is an even number, it means that e can only
0. That is, E = 0 and there is no carry. According to step 3, A = 5(6) D + G = r = 7 and it cannot contain carry characters that indicate D + G = 7, while D> = 5 and E = 0, A = 5.
D can only be equal to 6. According to step 1, t can only be equal to 2. G equals 1.
In step 4, N + R = B. According to Step 4, there is no carry. Therefore, n can only be equal to 0, 1, 2, and B can only be equal to, 8, and 9. N values all conflict with the preceding values. Therefore, L = 3 is impossible in step 2.Donald
+ Gerald ---------- Robert
When l = 8 is set to true:
(3)2a = e Indicates 2a + 1 = E, indicating that E is an odd number. (4) N + R = B (5) 0 + E = 0 indicate that E has two possibilities:
1. E = 0. 2.e= 9. If Step 3 shows that E is an odd number, it means that e can only
9. E = 9 indicates that step 4 has an increment and N> = 3. According to step 3, A = 4 is also described.(6) D + G = r = 7. If the input number is D + G + 1 = 7, it means that D can only be equal to 5 or 6. G can only be 1 or 0.
Assume that D = 6 then G can only be equal to 0, that is, G = 0. According to step t = 2, according to the analysis in step 2, n = 3, or equal to 5
If n = 3, B = 0, which is in conflict with G.
If n = 5, B = 2 and T are abrupt.
If D = 5, G = 1. According to Step 1 T = 0. According to Step 1 analysis, n = 6, B = 3, and finally O can only be 2. O = 2.
So the final result is. T = 0g = 1 O = 2 B = 3 A = 4 d = 5 N = 6 r = 7 L = 8 E = 9
Thinking of such a question is quite a test of the logic of our thinking. Being a Software Talent requires strong logic thinking capabilities. This is also an area for companies to examine software talents.
