方形三角形
一个正整数x是一个正方形三角形,如果存在两个不同的正整数y和z,则它们小于x,使得所有和 x + y x + z y + z 是完美的正方形。 例如30是一个正方形三角形数字,因为 30 + 6 = 6 2 30 + 19 = 7 2 6 + 19 = 5 2 您的任务是编写一些代码,该代码以正整数作为输入,并确定它是否为正三角形。您应该输出两个不同的值之一,如果输入的是正方形三角形,则输出一个,否则输入另一个。 这是代码高尔夫球,因此答案将以字节计分,而字节数越少越好。 测试用例 这是1000以下的所有正方形三角形数字 30,44,47,48,60,66,69,70,78,86,90,92,94,95,96,98,108,113,116,118,120,122,124,125,126,132,138,142,147,150,152,154,156,157,158,159,160,165,170,176,180,182,185,186,188,190,192,194,195,196,197,198,200,207,212,214,216,218,221,222,224,227,230,232,234,236,237,238,239,240,246,248,253,258,260,264,266,267,268,270,273,274,275,276,278,280,281,282,283,284,285,286,290,296,298,302,303,306,308,310,312,314,317,318,320,322,323,324,326,328,329,330,331,332,333,334,335,336,338,340,344,347,350,351,352,356,357,360,362,364,368,370,371,372,374,376,377,378,380,382,384,385,386,387,388,389,390,392,394,396,402,405,408,410,413,414,415,418,420,422,423,424,426,429,430,432,434,435,436,438,440,442,443,444,445,446,447,448,449,452,456,458,462,464,466,467,468,470,472,476,477,479,480,482,484,485,488,490,491,492,494,496,497,498,500,501,502,503,504,505,506,507,508,509,510,512,515,516,518,522,523,524,527,528,530,533,536,538,540,542,543,546,548,549,550,551,552,554,557,558,560,562,563,564,566,568,569,570,571,572,573,574,575,576,578,579,582,585,588,590,592,593,594,598,600,602,603,604,605,606,608,610,612,613,614,615,616,618,620,621,623,624,626,627,628,630,632,633,634,636,638,639,640,641,642,643,644,645,646,650,652,656,657,658,659,660,662,666,667,668,670,672,674,677,678,680,682,683,686,687,689,690,692,694,695,696,698,700,701,702,704,706,707,708,709,710,711,712,713,714,715,716,717,718,719,720,722,723,726,728,730,734,737,739,740,742,744,745,746,750,752,755,756,758,760,762,764,765,767,768,770,772,773,774,776,778,779,780,782,783,784,785,786,788,789,790,791,792,793,794,795,796,797,798,800,802,803,804,805,810,812,814,816,817,818,819,820,822,825,826,827,828,829,830,832,833,834,836,837,838,840,842,846,847,848,849,850,851,852,854,855,856,858,860,861,862,863,864,866,867,868,869,870,871,872,873,874,875,876,877,878,879,880,882,884,888,890,891,893,896,897,898,902,903,904,905,908,912,913,914,915,916,918,920,923,924,926,927,928,929,931,932,933,935,936,938,940,941,942,944,946,947,948,950,952,953,954,955,956,957,958,959,960,961,962,963,964,965,966,967,968,970,972,974,976,978,980,981,984,986,987,988,992,993,995,996,998 OEIS A242445
