program in C

Q3: In cryptarithmetic puzzles, mathematical equations are written using letters. Each letter can be a digit from 0 to 9, but no two letters can be the same. Here is a sample problem: SEND + MORE = MONEY A solution to the puzzle is S -9, R-8, O 0, M- 1, Y-2, E-5, N-6, D 7 Write a program that finds solutions to the cryptarithmetic puzzle of TOO + TOO + TOO + TOO GOOD The simplest technique is to use a nested loop for each unique letter (in this case T, O, G, D). The loops would systematically assign the digits from 0-9 to each letter. For example, it might first try- 0, O = 0, G 0, D 0, then T-0, 0-0, G-0, D-1, then T-0. O-0, G 0, D-2, etc. up to T 9. o 9, G-9, D-9. In the loop body test that each variable is unique and that the equation is satisfied. Output the values for the letters that satisfy the equation
