The **distinct difference** array of `nums` is an array `diff` of length `n` such that `diff[i]` is equal to the number of distinct elements in the suffix `nums[i + 1, ..., n - 1]` **subtracted from** the number of distinct elements in the prefix `nums[0, ..., i]`. Return _the **distinct difference** array of _`nums`. Note that `nums[i, ..., j]` denotes the subarray of `nums` starting at index `i` and ending at index `j` inclusive. Particularly, if `i > j` then `nums[i, ..., j]` denotes an empty subarray. **Example 1:** ``` **Input:** nums = [1,2,3,4,5] **Output:** [-3,-1,1,3,5] **Explanation:** For index i = 0, there is 1 element in the prefix and 4 distinct elements in the suffix. Thus, diff[0] = 1 - 4 = -3. For index i = 1, there are 2 distinct elements in the prefix and 3 distinct elements in the suffix. Thus, diff[1] = 2 - 3 = -1. For index i = 2, there are 3 distinct elements in the prefix and 2 distinct elements in the suffix. Thus, diff[2] = 3 - 2 = 1. For index i = 3, there are 4 distinct elements in the prefix and 1 distinct element in the suffix. Thus, diff[3] = 4 - 1 = 3. For index i = 4, there are 5 distinct elements in the prefix and no elements in the suffix. Thus, diff[4] = 5 - 0 = 5. ``` **Example 2:** ``` **Input:** nums = [3,2,3,4,2] **Output:** [-2,-1,0,2,3] **Explanation:** For index i = 0, there is 1 element in the prefix and 3 distinct elements in the suffix. Thus, diff[0] = 1 - 3 = -2. For index i = 1, there are 2 distinct elements in the prefix and 3 distinct elements in the suffix. Thus, diff[1] = 2 - 3 = -1. For index i = 2, there are 2 distinct elements in the prefix and 2 distinct elements in the suffix. Thus, diff[2] = 2 - 2 = 0. For index i = 3, there are 3 distinct elements in the prefix and 1 distinct element in the suffix. Thus, diff[3] = 3 - 1 = 2. For index i = 4, there are 3 distinct elements in the prefix and no elements in the suffix. Thus, diff[4] = 3 - 0 = 3. ``` **Constraints:** `1 <= n == nums.length <= 50` `1 <= nums[i] <= 50`",8 "public_test_cases": [9 {10 "label": "Example 1",11 "input": "nums = [1,2,3,4,5]",12 "output": "[-3,-1,1,3,5] "13 },14 {15 "label": "Example 2",16 "input": "nums = [3,2,3,4,2]",17 "output": "[-2,-1,0,2,3] "18 }19 ],20 "private_test_cases": [21 {22 "input": [23 44,24 1,25 46,26 10,27 5,28 7,29 50,30 2,31 44,32 32,33 1,34 26,35 34,36 21,37 33,38 30,39 5,40 6,41 33,42 12,43 13,44 1,45 3746 ],47 "output": [48 -17,49 -16,50 -14,51 -12,52 -11,53 -9,54 -7,55 -5,56 -4,57 -2,58 -2,59 0,60 2,61 4,62 5,63 7,64 8,65 10,66 11,67 13,68 15,69 16,70 1871 ]72 },73 {74 "input": [75 3776 ],77 "output": [78 179 ]80 },81 {82 "input": [83 17,84 31,85 15,86 24,87 8,88 5,89 41,90 12,91 33,92 23,93 44,94 3,95 33,96 45,97 45,98 44,99 35,100 37,101 2,102 31,103 11,104 38,105 5,106 10,107 4,108 48,109 35,110 1,111 40,112 3,113 13114 ],115 "output": [116 -22,117 -21,118 -19,119 -17,120 -15,121 -14,122 -12,123 -10,124 -9,125 -7,126 -6,127 -5,128 -4,129 -3,130 -2,131 -1,132 0,133 2,134 4,135 5,136 7,137 9,138 10,139 12,140 14,141 16,142 17,143 19,144 21,145 22,146 24147 ]148 },149 {150 "input": [151 13,152 1,153 39,154 29,155 17,156 39157 ],158 "output": [159 -3,160 -1,161 0,162 2,163 4,164 5165 ]166 },167 {168 "input": [169 14,170 21,171 34,172 43,173 2,174 3,175 48,176 17,177 1,178 16,179 40,180 50,181 27,182 36,183 6,184 28,185 26,186 2,187 44,188 33,189 43,190 6,191 13,192 20,193 21,194 4,195 6,196 41,197 38,198 19,199 39,200 42,201 14,202 7,203 35,204 4,205 39,206 12,207 6,208 10,209 25,210 18211 ],212 "output": [213 -32,214 -31,215 -29,216 -28,217 -27,218 -25,219 -23,220 -21,221 -19,222 -17,223 -15,224 -13,225 -11,226 -9,227 -8,228 -6,229 -4,230 -3,231 -1,232 1,233 2,234 2,235 4,236 6,237 7,238 8,239 8,240 10,241 12,242 14,243 15,244 17,245 18,246 20,247 22,248 23,249 24,250 26,251 27,252 29,253 31,254 33255 ]256 },257 {258 "input": [259 10,260 8,261 44,262 4,263 33,264 21,265 50,266 46,267 29,268 41,269 45,270 24,271 30,272 10,273 43,274 29,275 38,276 31,277 14,278 7,279 3,280 19,281 27,282 32,283 5,284 43,285 24,286 32,287 6,288 15,289 24290 ],291 "output": [292 -24,293 -22,294 -20,295 -18,296 -16,297 -14,298 -12,299 -10,300 -9,301 -7,302 -5,303 -4,304 -2,305 -1,306 0,307 1,308 3,309 5,310 7,311 9,312 11,313 13,314 15,315 16,316 18,317 19,318 19,319 20,320 22,321 24,322 25323 ]324 },325 {326 "input": [327 2,328 2,329 1,330 39,331 18,332 15,333 15,334 3,335 18,336 4,337 47,338 6,339 8,340 26,341 28,342 37,343 30,344 4,345 22,346 2,347 12,348 12,349 32,350 13,351 18,352 39,353 13354 ],355 "output": [356 -17,357 -17,358 -15,359 -14,360 -13,361 -12,362 -11,363 -9,364 -9,365 -8,366 -6,367 -4,368 -2,369 0,370 2,371 4,372 6,373 7,374 9,375 10,376 11,377 12,378 14,379 15,380 16,381 17,382 18383 ]384 },385 {386 "input": [387 44,388 41,389 17,390 11,391 3,392 21,393 7,394 1,395 23,396 48,397 39,398 41,399 44,400 26,401 28,402 46,403 46,404 9,405 5,406 29,407 38,408 5,409 1,410 4,411 17412 ],413 "output": [414 -18,415 -17,416 -16,417 -14,418 -12,419 -10,420 -8,421 -7,422 -5,423 -3,424 -1,425 0,426 1,427 3,428 5,429 6,430 7,431 9,432 10,433 12,434 14,435 15,436 16,437 18,438 19439 ]440 },441 {442 "input": [443 19,444 35,445 2,446 8,447 30,448 46449 ],450 "output": [451 -4,452 -2,453 0,454 2,455 4,456 6457 ]458 },459 {460 "input": [461 19,462 41,463 16,464 40,465 20466 ],467 "output": [468 -3,469 -1,470 1,471 3,472 5473 ]474 }475 ],476 "haskell_template": "distinctDifferenceArray :: [Int] -> [Int]\ndistinctDifferenceArray nums ",477 "ocaml_template": "let distinctDifferenceArray (nums: int list) : int list = ",478 "scala_template": "def distinctDifferenceArray(nums: List[Int]): List[Int] = { \n \n}",479 "java_template": "class Solution {\n public int[] distinctDifferenceArray(int[] nums) {\n \n }\n}",480 "python_template": "class Solution(object):\n def distinctDifferenceArray(self, nums):\n \"\"\"\n :type nums: List[int]\n :rtype: List[int]\n \"\"\"\n "481}
